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 If the speed of sound in this gas at NTP is 952 , then the heat capacity at constant pressure is
(Take gas constant R = 8.3 )
Since 4.0g of a gas occupies 22.4 litres at NTP, so the molecular mass of the gas is
As the speed of the sound in the gas is
where is the ratio of two specific heats, R is the universal gas constant and T is the temperature of the gas.
