Remember that the molecular mass is the mass of one mole or 6 X 10²³ molecules of the compound in question. For example:

A water molecule has a formula mass of 18 atomic mass units. 6 X 10²³ water molecules (or one mole of water molecules) weigh 18 grams.

Complete the table below with the following information at hand.
Na = 23, C =12, O =16, H =1.
