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.

it's filtration, but this is an assumption so my apologies if i got this

the answer is 75.0%.
