What is the mass of 4.25 liters of n2 gas at stp?
3.91 grams 4.65 grams 4.96 grams 5.31 grams

We know that 1 mole of anything has a volume of 22.4 liters.

And 1 mole of N2 gas has a weight of 28 grams.

Comparing them , we get the answer as 5.31

Answer : The mass of nitrogen gas at STP is, 5.31 grams.

Explanation : Given,

Volume of nitrogen gas = 4.25 L

Molar mass of nir=trogen gas = 28 g/mole

As we know that at STP,

1 mole of gas contains 22.4 L volume of gas

According to the question,

As, 22.4 L volume of gas present in 1 mole of gas

So, 4.25 L volume of gas present in mole of gas

Now we have to calculate the mass of nitrogen gas.

Therefore, the mass of nitrogen gas at STP is, 5.31 grams.
