Find the speed of sound in a mixture of `1` mole of helium and `2` mole of oxygen at `27^(@)C`

Find the speed of sound in a mixture of 1 mole of helium and 2 moles of oxygen at 27^(@)C . If the temperature is raised by 1K from 300K, find the percentage change in the speed of sound in the gaseous mixture. Take R=8.31Jmo l e^(-1)K^(-1) .

The speed of sound in hydrogen gas at certain temperature is v (m)/(s) Find the speed of sound in a gaseous mixture containing 2 moles of oxygen and 1 mole of hydrogen gas, at the same temperature. Assume the gases do no react at the ordinary temperature.

The speed of sound in a mixture of n_1=2 moles of He , n_2=2 moles of H_2 at temperature T=972/5 K is etaxx10m//s .Find eta .(Take R=25/3J /mole-K)

In a flask of volume 8.2 litres there is a mixture of "1" mole of N_(2) and 1 mole of He at 27^(@)C .The pressure exerted by the mixture in atmospheres is (R=0.082L atm K^(-1)mol^(-1))

A vessel of volume V contains a mixture of 1 mole of hydrogen and 1 mole oxygen (both considered as ideal). Let f_(1)(v) dv, denote the fraction of molecules with speed between v and (v+ dv) with f_(2)(v)dv , similarly for oxygen . Then ,

The temperature of the mixture of one mole of helium and one mole of hydrogen is increased from 0°C to 100°C at constant pressure. The amount of heat delivered will be
