Question

1 mole of C60 (solid, fullerene) on complete combustion forms __________ m3 of
CO2(g) at STP

(A) 60
(B) 60 × 22.4
(C) 60 × 22.4 × 10^−3
(D) 22.4

Answer 1

1 mole of C₆₀ (solid fullerene) on complete combustion forms __ m³ of CO₂ gas at STP.

solution : combustion of solid fullerene is ..

  C₆₀ (s) + O₂ (g) ⇒ 60CO₂ (↑)

here it is clear that one mole of solid fullerene on complete combustion forms 60 moles of carbon dioxide.

at stp, 1 mole of ideal gas = 22.4 L

so, 60 moles of ideal gas = 60 × 22.4 L

therefore the volume of CO₂ gas formed by the combustion of solid fullerene is 60 × 22.4 L
