Answer:
◆ Answer - n1 = 2 mol. n2 = 0.25 mol.
● Explaination - Molar mass of MgO is given by - M = 24 + 16.
M = 40 g/mol.
(i) W1 = 80 g. Number of moles of MgO will be - n1 = W1/M. n1 = 80/40.
n1 = 2 mol.
(ii) W2 = 10 g. Number of moles of MgO will be - n2 = W1/M. n2 = 10/40.
n2 = 0.25 mol.

Answer:
✓ MgO -- Magnesium Oxide
• Molar mass of magnesium = 24
& Oxygen = 16
Total = 24 + 16 = 40 g
1 mole of MgO contains 40g
--- moles of MgO contains 80g
cross multiply
the answer will be 2 moles.
