Question

Air is contained in an open vessel at 2 7 ∘ C . It is heated to 18 6 ∘ C when 3 moles of the air contained in the vessel is expelled. Assuming there is 2% increase in the volume of container, if x moles of air were, initially present in the vessel. Find the value of 3 x

Let initial moles = n 1 ​ . Volume = v 1 ​ . Temp = 300 K . ​ Final moles = n 1 ​ − 3 = n 2 ​ , Volume = 100 102 v 1 ​ ​ temp = 459 k n 1 ​ T 1 ​ v 1 ​ ​ = n 2 ​ T 2 ​ v 2 ​ ​ ( pconstant ) , n 1 ​ × 300 v 1 ​ ​ = n 2 ​ × 459 100 102 v 1 ​ ​ ​ 459 n 2 ​ = 306 n 1 ​ 153 n 1 ​ = 3 × 459 n 1 ​ = 3 × 3 = 9 ​
