Question

Water (H2O) forms when hydrogen gas (H2) and oxygen gas (O2) react according to the equation below: 2H2 +O2 → 2H2O What mass of water forms when 1.45 × 10-3 g O2 react completely? (Molar mass of O2 = 32.00 g/mol; molar mass of H2O = 18.02 g/mol)

Answer 1

The answer is A

1.63 × 10-3 g

Answer 2

the mass of water that forms is1.63 * 10^-3g
