Question

4.0 g of a gas occupies 22.4 litres at NTP. The specific heat
capacity of the gas at constant volume is 5.0JK⁻¹. If the
speed of sound in this gas at NTP is 952 ms⁻¹, then the
heat capacity at constant pressure is (Take gas constant R
= 8.3 JK⁻¹ mol⁻¹) [2015 RS]
(a) 7.5 JK⁻¹ mol⁻¹
(b) 7.0 JK⁻¹ mol⁻¹
(c) 8.5 JK⁻¹ mol⁻¹
(d) 8.0 JK⁻¹ mol⁻¹
