$A$ container contains equal masses of $H_2$,$He$,$CO_2$,and $Ne$ at a certain temperature. Which of the following gases exerts minimum partial pressure?

Between $NH_3$ and $CO_2$,which one will diffuse faster? What will be the ratio of their rates of diffusion?

If $H_2S$ and $NH_3$ gases are released simultaneously from a cylinder through a small hole,which gas will be detected first and why?

When the pressure of $1 \ mol$ of ammonia gas changes from $1 \ atm$ to $0.5 \ atm$ at constant temperature,the number of molecules will:
