Water decomposes to hydrogen and oxygen gas as shown in
the following reaction:
2H20 (g) → 2H2 (g) + O2 (g)
Given a 6.80 g sample of H20 (MM = 18.0 g/mol), how many
grams of oxygen (MM = 32.0 g/mol) is produced, assuming the
decomposition goes to completion?

Answer:

6.04 g O2

Explanation:

6.80 g H2O x (1 mol/18.0 g) x (1 O2/2 H2O) x (32.0 g/1 mol) = 6.04 mol O2
