Question

7.In a flask of 'V'litres, 0.2moles of O2,
0.4 moles of N2, 0.1 moles of NH3
and 0.3 moles of He gases are
present at 27 degree celcius. If the
total pressure exerted by these gases
is 1 atm,the partial pressure exerted
by N2 gas is *
*
O 0.1 atm
O 0.2 atm
O 0.3 atm
O 0.4 atm​

Answer 1

Answer:

In a flask of volume V litres, 0.2 mol of oxygen, 0.4 mol of nitrogen, 0.1 mol of ammonia and 0.3 mol of helium are enclosed at 27^∘C . If the total ...

Answer 2

Answer:

O 0.4 atm

Explanation:

As we know,

Partial pressure = Mole fraction x total pressure

∴P  N₂ = X N₂ ∗ P total

 P N₂ = 0.4 / 0.2 + 0.4 + 0.1 + 0.3 * 1

P N₂ = 0.4 atm

∴ O 0.4 atm is the correct option.

Hope it helps you....
