You are a gift from God😭🙏🏻

Amazing! My professor was using a different method that was distinctly confusing, and after watching your video, I feel like I could try to solve more problems.. thank you.

Thanks for the kind words. It's been a rough week and I appreciate the positive note :)

Wonderful explanation

Absolutely perfeeeect

why is NH3 the solute and not the solution?

[@wongoli]

Thx. Chem professor talks more about theory and politics than how to solve the actual problems that are on the test -___________________-

I am really struggling with identifying and sorting my numbers. Is there a way of looking at a problem like this and breaking up my steps? I see how you broke yours down but for me, how can I look at this and know off the bat how to break it down. I had a quiz and I just didn't know how to set it up. I thought my professor would have the formulas laid out for us but he didn't. We had Delta H of vaporization, Freezing and boiling points.

John - Practice is really the key to being able to solve problems. Work problems out on paper so you can see how the information is sorted and how you set it up. When you get a problem wrong, don't erase. Try again and then compare the right and wrong attempts to help you identify errors you made. We often learn more from our mistakes than from getting a problem right the first time.

Thank you for your response and advise. I'm in Chem 2 and I took Chem 1 about a year and a half ago. So I'm trying to catch up to what I've remembered from Chem 1. I've been looking at my notes and watching videos. I'm trying to catch up to Molarity, Molality, Mass percentage, Mole fraction and trying to apply to the questions and this is where I can lose track of which formula to use.
