A cylinder contains 0.3 moles of `N_(2)`, 0.1 mole of `O_(2)` and 0.1 mole of helium. If the total pressure is one atm, what is the partial pressure of oxygen in mm Hg:-

A vessel contains 0.1 mol e of He, 0.1 mole of O_(2) and 0.3 mole of N_(2) . The total pressure is 1 atomosphere. The pressure exerted by O_(2) is

Air contains 79% N_(2) and 21% O_(2) by volume. If the barometric pressure is 750 mm Hg . The partial pressure of oxygen is

Air contains 79% N_(2) and 21% O_(2) by volume. If the barometric pressure is 750 mm Hg . The partial pressure of oxygen is

At STP, a container has 1 mole of Ar, 2 mole of CO_(2) , 3 moles of O_(2) and 4 moles of N_(2) . Without changing the total pressure if one mole of O_(2) is removed, the partial pressure of O_(2)

At STP, a container has 1 mole of Ar, 2 mole of CO_(2) , 3 moles of O_(2) and 4 moles of N_(2) . Without changing the total pressure if one mole of O_(2) is removed, the partial pressure of O_(2)

If 1 mole of H_(2) , 2 moles of O_(2) and 3 moles of N_(2) are mixed in a vessel and total pressure was found to be 12 atm then the partial pressure exerted by N_(2) in the vessel will be

If 1 mole of H_(2) , 2 moles of O_(2) and 3 moles of N_(2) are mixed in a vessel and total pressure was found to be 12 atm then the partial pressure exerted by N_(2) in the vessel will be

At STP a contains has 1 mole of H_(2) 2 mole Ne, 3 mole O_(2) and 4 mole N_(2) . Without changing total pressure if 2 mole of O_(2) is removed, the partial pressure of O_(2) will be decreased by

At STP a contains has 1 mole of H_(2) 2 mole Ne, 3 mole O_(2) and 4 mole N_(2) . Without changing total pressure if 2 mole of O_(2) is removed, the partial pressure of O_(2) will be decreased by
