1. \(4.0\, g\) of a gas occupies \(22.4\, litres\) at NTP. The specific heat capacity of the gas at constant volume is \(5.0\,J K^{−1}mol^{ −1}\). If the speed of sound in this gas at NTP is \(952\,ms^{−1}\), then the heat capacity at constant pressureis (Take gas constant \(R = 8.3\,J K^{−1}mol^{ −1}\))
