I hope you will read this, but I would like to know (14:09) why is the 150mL of H2O was the solute? From what I have solved from that problem it is supposed to be 19.8g of methanol instead of the water so the mass percent of the water is supposed to be 11.7% not 88.3%. I am a fan of your videos I hope you could correct this for us.

It's not that the water really becomes the solute, The mass percent could also be of the solvent rather than the solute. Water will not be solute. The solute is always the one in lower quantity. Don't write it in the exam that water becomes the solute

To get the v% ,you have to first get the volume of solution.which is volume of solute + volume of solvent,i.e 150ml volume of solvent plus 25ml volume of soulute.. although methanol and water are substances that can be used in dissolving i.e they can both be seen as solvent.But, since the volume of water in this case is higher than that of methanol,he simply made methanol the solute and water the solvent.

Thanks for the videos. I have been following you a good number of times. And I must admit that you are the best. But have a little concern about the second problem of the lesson. Calculating a volume percent. I was told that mass is additive when you are working with percentage concentrations. But volume is not. But I noticed problem 2 while finding V% you added the 25 ml plus the 150 ml to give you 175ml. Why is that so? If the v% formula is V% is the volume of solute divided by the volume of solution. I am not challenging you but just a concern and I want to learn. Thanks.
@jameyanderson4294

Agreed--masses are strictly additive while volumes are only approximately additive. The density of the final solution is needed figure out this problem.
