Table titled "Formation of Water" with four rows down the left side, labeled Equation, Amount, Molar Mass, and Mass. The information for Amount, Molar Mass, and Mass is given for the hydrogen and oxygen atoms in the chemical equation for water, as follows: Equation: 2H2 + O2 = 2H20 Amount: 2 moles + 1 mole = 2 moles Molar Mass: 2.0 + 32.0= 18.0 Mass: 4.0 + 32.0 = 36.0
