Answer:
0.34 moles of oxygen consumed 0.68 moles of magnesium
Explanation:
Given data:
Moles of magnesium = ?
Moles of oxygen = 0.34 mol
Chemical equation:
2Mg + O₂ → 2MgO
Now we will compare the moles of oxygen and magnesium:
O₂ : Mg
1 : 2
0.34 : 2×0.34 = 0.68 mol
Thus 0.34 moles of oxygen consumed 0.68 moles of magnesium.
