How to find the number of molecules in a compound

Asked by admin @ 10/11/2021 in Chemistry viewed by 308 People

Calculate the number of moles of each compound, given the number of molecules.

If you need to make a number a superscript, put a ^ in front of the number. For example, 2.45 x 1022 would be written as 2.45 x 10^22.
