$2.0 \ g$ of $H_2$ diffuses through a porous container in $10 \ minutes$. How many grams of $O_2$ would diffuse from the same container in the same time under similar conditions (in $.0$)?

What are the measurable properties of a gas?

$A$ gaseous mixture was prepared by taking equal moles of $CO$ and $N_2$. If the total pressure of the mixture was found to be $1 \ atm$,the partial pressure of the nitrogen $(N_2)$ in the mixture is $...$ $atm$.

$A$ person living in $Shimla$ observed that cooking food without using a pressure cooker takes more time. The reason is that at high altitude:

Write the formula for partial pressure.

$360 \ cm^3$ of a hydrocarbon diffuses in $30$ minutes, while under the same conditions $360 \ cm^3$ of $SO_2$ gas diffuses in one hour. The molecular formula of the hydrocarbon is
