Equal number of hydrogen and helium molecules are kept in two identical gas jars at the same temperature .What will be the ratio of the pressures of the gases in the two jars?

Explanation

Pressure is the same in both the jars. As per Avagadro.s law all gases of equal volume contain the same number of molecules under indentical values of temperature and pressure. In this example ,volume temperature and number of molecular are the same. SO the pressure will be equal in the two jars are the ratio is `1:1`.
