What is the answer to #11 and how do you find it?

The answer to number 11 is 76.04 g!! I have attached a picture showing you my work. You want to go from mass to moles, so i first wrote down the info that we know- 2.00 mol. I then determined the mass of H2O2 in one mol

I did this by looking at the periodic table and looking at the atomic mass (bottom number) for each element and it’s quantity.

I then multiplied 2.00 by 38.03 because the bottom number on the fence post (1 mol) cancels out! I hope this helps you!

Ithink d hope that
