Question

calculate volume occupied by in 67.2 litres of co2 gas at 1 atmosphere​

Answer 1

Explanation:

By Avogadro law,

22.4 liter of any gas at STP=1mole

=6.022×10

23

molecules of gas

=NA (Avogadro number)

So, in 67.2 L of NH

3

=?

22.4 L of NH

3

=N

A

1 L of NH

3

=

22.4

NA

67.2 L of NH

3

=

22.4

67.2

×NA

=3N

A

molecules

Now, each molecule contain 4 atoma

Number of atoms =4×3N

A

=12N

A
