Question

The number of mole of nitrogen in one litre of air containing

Answer 1

Answer:

The volume of nitrogen in the mixture is:

10% of the mixture = 10/100 x 1 liter

= 0.1 liters

Use ideal gas law to calculate the moles of the nitrogen gas.

Ideal gas law states that 1 mole of an ideal gas occupies 22.4 liters by volume.

Therefore, If 22.4 liters gives 1 mole,

then what will 0.1 mole give? = ( 0.1 x1/22.4) liters.

(use cross multiplication to come up with the answer)

= 0.1/22.4

= 4.46 x 10^-3
