I completely agree!! My Chem teacher just goes over basic information for the class and expects us to figure out every other concept on our own.. so being able to watch these and work out the problems so I actually understand really helps!!
Thank you for this thorough yet brief explanation of this ALEKS topic! I really appreciate that you gave alternate methods to solve the problem but explained your reasons for the methods you used.
I assume you mean using moles and the ideal gas law to calculate partial pressures. That may be how ALEKS explains it. However, you will get the same answer using either method.
@@RoxiHulet if 4dm3 of methane at 2.02 *10^5 pa and ethane of 1.25dm3 at pressure of3.5 *10^5 and 1.5dm3 of propane at a pressure of 1.01 *10^5 were all pumped into 10dm3 volume calculate partial of each components I found the total pressure which is around 1.3567 10^5 i couldnt find the partial pressure despite having answers for it because i need to know the method and i hope you can make video instead of writing replies which normally dont visually explain me thank you !
@@riazijabar5296 the pressures of each gas are independent of the other gases in the final mixture, so you can (and should) treat this as 3 separate problems. You know the initial pressure and volume of each gas. The final volume of each gas is 10 dm3 because each gas expands to fill the entire container. You can calculate the final pressure using P1V1 = P2V2, where 1 = initial P & V and 2 = final P & V. Does that make sense?
as a college student, these are literally the best videos ever i wish you were my professor thank you for these!
Thank you! That’s so nice of you to say!

Yes, queen. You go calculating partial pressure in a gas mixture!

Thank you for breaking this down and clarifying what the question is asking for.
love this! love you!
Why did you do 14+14 2x and 16+16?
I’m not sure what you’re asking about, could you give more detail?
Alecks wants you to use the mols of each molecule, not the fraction part for the total and partial pressures btw :)

@@RoxiHulet do you have WhatsApp so that i can send a particular problem that i have for you to solve im just kinda struggling with it
@@riazijabar5296 nope, but if you describe it here, I will do my best to help!

Thank you so much, this helped me a lot because i can’t move on with this topic.
Glad it was helpful!
