Answer:
134.4 g of Mg
Explanation:
reaction:
2Mg + O2 ➡️ 2MgO
1) find the mol of MgO
mol = mass / molar mass
mass = 224 g
molar mass = 24+16 = 40
mol = 224 / 40
= 5.6 moles
2 mol = 5.6 moles
2) find the mass of Mg
mass = mol × molar mass
mol = 5.6
molar mass = 24
mass = 5.6 × 24
= 134.4 g
Cause their are both have difference s
