And you'll see why in a second. So let's find the molar mass of our ethylene glycol, our solute. So basically, we add up the atomic mass of each atom. So, since we have two carbon atoms, we multiply two times 12 grams/mol for carbon. Since we have two O atoms, we multiply two times 16 grams/mol for oxygen. And since we have six H atoms, we multiply six times 1 gram/mol for h and we get all these guys up 62 grams/mol.
