I was confused at first because I know that I subscribed to you years ago. Then, I realized that this channel is specifically for the MCAT. You've helped me a lot over the years. Can't wait to watch more of your MCAT review videos. Thank you for all that you do!

You're very welcome!

loved the trick part about diol! Very mcat based question

[@Leah4sciMCAT]

Glad you liked it!

Here is how I remembered them because I was confused at first. Molecular is more numbers... and therefore empirical is less.

[@Leah4sciMCAT]

ooh I like that! Thanks for sharing it

I have a question. If we If we were given the molar mass in a problem and we had to find the molecular formula, would we multiple the molar mass by the empirical formula ?

basically where are you from , teacher

[@Leah4sciMCAT]

How does this relate to the MCAT?

[@lulaalder8254]

Hi Leah,
I was wondering if you had some advice about MCAT math practice. I'm using the Princeton Review, and while I think it's great so far, I am not a quick to figure out math as you have done in the video. What should I do? My main concern is really improving that to be quick and correct.
Thank you!!!
