2 Mg(s) + O2(g) → 2 MgO(s)

Calculate the amount of MgO produced from each reactant and determine the limiting reactant:

mass Mg (molar mass) → moles Mg (mole-to-mole comparison) → moles MgO (molar mass) → mass MgO

molar mass Mg = 24.305 g/mol
molar mass MgO = 40.305 g/mol

mass MgO = 16.75 g MgO

mass O2 (molar mass) → moles O2 (mole-to-mole comparison) → moles MgO (molar mass) → mass MgO
