$A$ neon-dioxygen mixture contains $64 \ g$ $O_2$ and $160 \ g$ $Ne$. If the total pressure is $25 \ bar$,calculate the partial pressure of dioxygen. (in $bar$)

For which of the following gas mixtures does Dalton's law of partial pressure $NOT$ apply?

At $T \ K$,equal weights of $H_2, D_2$,and $T_2$ are present in a closed vessel. The pressure exerted by this gaseous mixture is $P \ atm$. The ratio of partial pressures of $T_2, D_2$,and $H_2$ is approximately. ($H, D$ and $T$ are isotopes of hydrogen).

What is the relative rate of diffusion of a gas (molecular weight = $98$) compared to hydrogen?

Which of the following mixtures of gases cannot be used to demonstrate Dalton's Law of Partial Pressures?

Which of the following gas mixtures will not obey Dalton's law of partial pressure?
