The problem here is that cement is not a pure substance, it is a mixture. Therefore, its properties are constant and would change according to the mixture. Thanks for watching.
Find the density and the specific gravity is the same without the units. Example: 9,81 g/ml to 9.81 Density and specific gravity respectfully. Thank you for watching!
But some literatul, explain me, SG is ratio of its weight and volume, instead of ratio density of substance and density of water. Could you explain me pls ?.
Can somebody show me the method that compares Weights/Gravity ?? I EXPECT Newtons and m/s^2 in their calculations ... if I only see m^3 and kg, then they're only using Volume and Mass, despite their claims. I also EXPECT the Specific Gravity of a substance to be different on the Moon, as the substance will have a different Weight on the Moon (Moon has a different Gravity). Is Specific Gravity different on the Moon ? Gravity is the SAME for all things (9.8m/s^2) - elephants, lead and feathers in vacum fall at the same speed. I have a strange feeling that whoever invented this Specific Gravity didn't know this ... Gravity is the same, how can sombody invent Specific Gravity :-? ....
The reality of specific gravity is that it is not about the acceleration of matter. In most cases it's about mass per volume because mass doesn't change for the most part.
I am having a huge problem with this specific problem. c) Calculate the mass of a 0.253-mL sample of a liquid with density 0.660 g/mL The website i'm doing the homework on says i am getting my answer in sq ML and i dont understand how
At 600 gals by-weekly of NaOCI I would like to makes sure I am getting what I pay for. How can I find the Specific Gravity on the trade % of NcOCI. the range would be from 1% to 15%. will the temp rating on the hydrometer play a roll on my reading?
what if i only have the the height of the container, its dimension, mass of the container with and without fluid. and i have to find the specific weight, specific gravity and the density?
Mariel Serrano You can find the volume by multiplying the base area by the height. The mass of the fluid is the container with the fluid minus the the container without the fluid. Now that you have mass and volume you can find the density. Remove the units from density and you have the specific gravity. In order to calculate specific weight, you must multiply the mass by gravity then divide by the volume.
Density and specific gravity have the same digits but the two are not same by definition. Density is the ratio of mass to volume and the units are usually kg/L. Specific gravity is the ratio of the density of a substance to the density of water and is unit less. Both have uses in lab work.
My dang chem lab book says that density of water is 0.9990090 g/mL. An example problem is 6g/100.0mL and I get the density is 0.06g/mL. But the answer for the example says "the hydrometer measures the specific gravity at 1.0400! I wish it was like how you explained it lol
You are AWESOME!!!!!!! ;)
you explained in 5 minutes what my teacher has failed to explain in 1 week on this topic thank you.
Thank you for watching and commenting.
you just got wrong teacher
thank you mister causey
You're welcome.
You have just been awarded a Like for your clarity in explaining Specific Density.
I'm studying fundamentals to HVAC and this has helped me out a lot
Thank you for watching and taking the time to comment!
It’s fantastic mr.causey 🙏🏻😊.
Thank you.
what is the specific gravity of rubber seed oil at 50 degree C ?
This was very clear and easy to understand. Thank you so much!
Hello Mr. Cassey.
Thanks for this.
Can I have a copy of this presentation?
Thank you :)
A wonderful explanation!
Thank you!
Thank you
You are welcome!
If specific gravity is mass density without units..
Why is the specific gravity of cement=3.15, when its mass density is 1.44gm/cc??
The problem here is that cement is not a pure substance, it is a mixture. Therefore, its properties are constant and would change according to the mixture.
Thanks for watching.
how do you solve specific gravity if there is no density water and density substance in the given?
Find the density and the specific gravity is the same without the units. Example: 9,81 g/ml to 9.81
Density and specific gravity respectfully.
Thank you for watching!
you just made my day !! thank you for this video !!
Thanks so much. This is helping me with my vet tech chemistry class!
Thanks.
You're welcome.
But some literatul, explain me, SG is ratio of its weight and volume, instead of ratio density of substance and density of water.
Could you explain me pls ?.
Awesome you are Sir 💘
Thank you.
GREAT GREAT VIDEO. THANKS A LOT DEAR SIR.
What if the density of the water is given?
Here: If the density of a liquid is 0.80g/mL, what is its specific gravity?
The specific gravity would be 0.80
Thanku
You're welcome!
Can somebody tell why the ratio of 2 densities is called "specific gravity", when it has NOTHING to do with gravity ?
Well, it is more than likely because one of the methods for doing this ratio is comparing the weights of two substances and weight involves gravity.
Can somebody show me the method that compares Weights/Gravity ?? I EXPECT Newtons and m/s^2 in their calculations ... if I only see m^3 and kg, then they're only using Volume and Mass, despite their claims.

weight has a lot to do with specific gravity and the amount of densities it has
god bless you for this video
Oh, thank you.
And Mass equal Volume divided density? Thank you!
Mass equals density times volume. Thanks for watching.
I couldn't sleep because of this question. Lol
Thank you!
You're welcome! Thank you so much for watching.
wha-
Thank you so much!!!
Is density of liqiuid change with temperature
Yes
Thanks a lot, very helpful
You're welcome. Thanks for commenting.

To find mass you multiply the density to the volume.
At 600 gals by-weekly of NaOCI I would like to makes sure I am getting what I pay for. How can I find the Specific Gravity on the trade % of NcOCI. the range would be from 1% to 15%. will the temp rating on the hydrometer play a roll on my reading?
the motor in my car makes 400 Hp, how much fuel (gasoline) will it need to produce just that??..
tnks.
ur videos are great! ty keep with this plz
This guy sounds like the Eugene from adventures in odyssey
No, he sounds like me. Thanks for watching.

Mr. Causey it is okay that my specific gravity is around 1800?
So specific gravity of an object is equal to its density??
The numbers are the same but the units cancel out. It is a ratio between the density of a substance and the density of water.
Can the density of a person be calculated? And once calculated how can it be change?
Sure. It could change by gaining or losing mass.
thanks. educative
present sir
Really informative.
You made a comment on Lying Excuses - Mighy Sparrow
if both density and SG are same , then why we take density instead of SG and vice versa in daily testing.
Density and specific gravity have the same digits but the two are not same by definition. Density is the ratio of mass to volume and the units are usually kg/L. Specific gravity is the ratio of the density of a substance to the density of water and is unit less. Both have uses in lab work.
Thank you sir
You're welcome! Thank you so much for watching.
Can anybody tell me that why boat floats on water.. Is that bcoz its density is less than 2
A boat floats because it's mass to volume ratio is less than 1.0 g/mL.
Why large ship with bigger density than water also float?
Good question. Density is mass per volume. Although the ship has a large mass it has an even greater volume thus its density is less than water's.
You sound like Jimmy from South Park
Hmmm! Usually people say Michael J Fox.
My dang chem lab book says that density of water is 0.9990090 g/mL.
An example problem is 6g/100.0mL and I get the density is 0.06g/mL. But the answer for the example says "the hydrometer measures the specific gravity at 1.0400! I wish it was like how you explained it lol
The difference is that I was using distilled water and the value you are using probably had some impurities.
Oh okay thanks!
It's clear, ratio of substance density with water density is SG.
thank you
You're welcome.
Per million?!!
Thank you!
