The volume occupied by 4 . 75 g of acetylene gas at 50 ° C and 740 mm Hg pressure is ____________ L . (Rounded off to the nearest integer) [Given R = 0 . 0826 L atm K - 1 mol - 1 ]
Correct answer
0
Step-by-step solution
Given mass = 4 . 75   g ⇒ C 2 H 2 g ⇒ Moles = 4 . 75 26   mol Temperature = 50 + 273 = 323   K P = 740 760 atm R = 0 . 0826 ℓ   atm mol   K ⇒ V = nRT P = 4 . 75 26 × 0 . 0826 × 323 740 760 ⇒ V = 96314 . 078 19240 = 5 . 0059 ℓ ≃ 5 ℓ
