'Equal volumes of all gases at the same temperature and pressure contain equal number of molecules'. This law is called as

In the gas equation, $$PV=nRT$$:

Among the following substances, the lowest vapour pressure is exerted by:

Which of the following is correct?

$$3$$ moles of $$P$$ and $$2$$ moles of $$Q$$ are mixed, what will be their total vapour pressure in the solution if their partial vapour pressures are $$80$$ and $$60$$ torr respectively?

The vapour pressure of a solvent at $$293$$K is $$100$$ mm Hg. Then the vapour pressure of a solution containing $$1$$ mole of a strong electrolyte $$(AB_2)$$ in $$99$$ moles of the solvent at $$293$$ K is:

According to Avogadro's hypothesis, equal volumes of gases under the same conditions of temperature and pressure will contain:

A solution at $$20^o$$C is composed of $$1.5$$ mol of benzene and $$3.5$$ mol of toluene. If the vapour pressure of pure benzene of pure benzene and pure toluene at this temperature are $$74.7$$ torr and $$22.3$$ torr. respectively, then the total vapour pressure of the solution and the benzene mole fraction in equilibrium with it will be, respectively.

If the absolute temperature of a gas is doubled and the pressure is reduced to one-half, the volume of the gas will

For an ideal gas, a number of moles per liter in terms of its pressure P, gas constant R and temperature T is:
