What volume of nitrogen gas (N2) is equal to 3.42x1022 molecules of this substance?

Answer : The volume of nitrogen gas equal to molecules of this substance is, 1.27 liters.

Explanation :

First we have to calculate the moles of nitrogen gas.

As, molecules present in 1 mole of nitrogen gas

So, molecules present in mole of nitrogen gas

Now we have to calculate the volume of nitrogen gas.

As we know that, 1 mole of substance occupies 22.4 L volume of gas at STP.

As, 1 mole of nitrogen gas occupies 22.4 L volume of nitrogen gas

So, 0.0568 mole of nitrogen gas occupies volume of nitrogen gas

Therefore, the volume of nitrogen gas equal to molecules of this substance is, 1.27 liters.
