is this a joke?

obviously, one adds the AW of the constituent atoms, making sure that all the atoms are accounted for

For instance, C12H24O has a molar mass of ROUGHLY:

12 x 12 = 144 +
1 x 24 = 24 +
16 x 1 = 16 =

144 + 24 +16 = 184 grams per mole.

I realize the above AW are only gross approximations, but I've been doing much math online lately, and I simply elected to skip the extra work.

IIRC, C = 12.0107 grams per mole, H = 1.0079 grams per mole, and O = 15.9994 grams per mole -- but check that before you use those numbers.

adding

But you have to be sure to add them in the right proportion. For example water has 2 hydrogens and 1 oxygen, so you must add 2 atomic weights of hydrogen, and one of oxygen.

Adding up Please be sure that you have to correct number specified by the compound formula.
