when putting the distiled water can you use a pipete the bottles for the water my college provides really suck and you it either all pours out or doesnt pour out so its hard to get accurate and you have to start all over if you use too much water
So you now know the amount, in moles, of sodium chloride in 250cm3. From this, you can work out the moles in 25cm3 by dividing by 10 (due to 250/25)? Is that correct
This video is incredible, thank you for explaining the practice so clearly. It was very helpful!!!!!
You're so welcome! Thanks for the feedback :)

Of course. I always get my students to use a dropping pipette for the last few mL of water when making up to the mark in the volumetric flask :)
Is this video mostly to do with how you should do a practical like in ISA's?Thank you in advance!
Hii sir How to melt the rod in chemical to use

And then you can do the relevant calculations with that mol amount?
Yup
Alright, thank you for the video. Was very helpful!
Glad to hear it
Thankyou soo much sir

when you measured the mass, did you take in consideration of the weight of the weighing boat?
nerd
The balance was set to 0 after the weighing boat was put on,so it was only the mass of the sodium chloride measured I think?
