Question

find the molar masses of the following compounds
LII

Answer 1

Explanation:

Multiply the atomic weight (from the periodic table) of each element by the number of atoms of that element present in the compound. 3. Add it all together and put units of grams/mole after the number. For many (but not all) problems, you can simply round the atomic weights and the molar mass to the nearest 0.1 g/mole
