16.00 grans One to Two Formula: Two moles of hydrogen combine with a 21.008 Hj 2.016 grams General Formulas. The formula masses for all compounds are calculated by multiplying each element by its subscript. The subscript of an element indicates the number of times the element appears in the compound. 1.000 Water, H20 contains 2 hydrogen atoms for each oxygen atom. The formula mass is calculated by adding 2 times the mass of hydrogen and 1 times the mass of...
