Finding the molar mass of a compound is often the first step in more complicated chemistry problems. When we say "molar mass," we mean the mass of 1 mole of that compound. Sometimes it's called the Gram molecular mass . We'll also explain what is meant by gram formula mass. That's a lot of terms that all sort of mean the same thing - so it's no wonder people get confused. We'll work through 5 examples. We'll be your very own homework tutor for chemistry!
