Question

How many molecules are in 22.4 l of Nitrogen gas at STP

Answer 1

The molecules in 22.4 l of Nitrogen gas at STP are 6.022 × 10²³.

Given:

22.4 l of Nitrogen.

To Find:

The molecules are in 22.4 l of Nitrogen gas at STP.

Solution:

To find the molecules are in 22.4 l of Nitrogen gas at STP we will follow the following steps:

As we know,

22.4 litre at STP ( Standard temperature pressure ) = 1 mole of any gas.

So, 22.4 litres of nitrogen at STP = 1 mole of nitrogen.

1 mole =

$6.022 \times {10}^{23} molecues$

Now,

Number of molecules in 22.4 l or 1 mole of N2 gas at STP =

$6.022 \times {10}^{23} molecues$

Henceforth, the molecules in 22.4 l of Nitrogen gas at STP are 6.022 × 10²³.
