What is the equation?

Question

What is the minimum mass of magnesium that would need to be heated with an excess of oxygen, to make 150 g of magnesium oxide?

Answer 1

Balanced Equation: 2 Mg + O₂ --> 2 MgO

Relevant Info: Molar Mass of Mg = 24.31 g/mol

Molar Mass of MgO = 40.30 g/mol

Stoichiometry: 150g MgO × (1 mol MgO / 40.30g MgO) × (2 mol Mg / 2 mol MgO) × (24.31 g Mg / 1 mol Mg) =

Final Answer: 90.48g Mg
