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 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)

At STP, a container has 1 mole of He, 2 mole Ne, 3 mole O_(2) and 4 mole N_(2) without changing total pressure if 2 mole of O_(2) is removed. Calculate the percentage decrease in 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

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:-
