Magnesium burns in air with a dazzling brilliance to produce magnesium oxide: 2Mg (s) + O₂ (g) → 2MgO (s)
When 2.00 g of magnesium burns, the theoretical yield of magnesium oxide is __________ g.

Question

Quizplus · Accepted Answer

The molar mass of Mg is 24.31 g/mol and MgO is 40.31 g/mol. Theoretical yield = (2.00 g Mg) * (1 mol Mg/24.31 g Mg) * (2 mol MgO/2 mol Mg) * (40.31 g MgO/1 mol MgO) = 3.32 g MgO.
