Stoichiometry (article)
Multiplying the number of moles of H A 2 SO A 4 by this factor gives us the number of moles of NaOH needed: 3.16 × 10 − 2 mol H 2 SO 4 × 2 mol NaOH 1 mol H 2 SO 4 = 6.32 × 10 − 2 mol NaOH. Notice how we wrote the mole ratio so that the moles of H A 2 SO A 4 cancel out, resulting in moles of NaOH as the final units.

Step 4: Convert moles back to 'grams' using molar mass of O2. Molar mass of O2 = 2 (atomic mass of O) = 2 (15.999) = 31.998 g i.e. 1 mole of O2 = 31.998 g of O2 therefore, 1.695 moles of O2 = 31.998 g/mol x 1.695 mol = 54.236 g. Answer: If 138.6 g of KClO3 is heated and decomposes completely, 54.236 g of oxygen gas will be produced.
