Question

at stp what is the volume occupied by 7g of nitrogen

Answer 1

Molecular weight of Nitrogen gas (N2)= 28g. And we know that, Moles = Given mass ( in grams)/ Molecular weight. So, at STP, 1 mole occupies 22.4L, so 0.25 moles will occupy: Volume= 22.4×0.25= 5.6L (ANS).

Answer 2

5.6 litres of volume will be occupied by the gas.

Explanation:

• Nitrogen is a gas that is found in atmosphere in maximum amount.

• Nitrogen has the atomic weight of 14 and molecular weight of 28, being diatomic molecule.

• So the weight of 1 mole of nitrogen is 28 grams.

• So, 28 litres of nitrogen has 1 mole molecules in it.

• So, 7 litres of nitrogen will have 0.25 mole of nitrogen in it.

• At Standard temperature and pressure, 1 mole of an ideal gas occupies 22.4 litres of volume.

• So, 0.25 mole of gas will occupy$\frac{22.4}{0.25}$litres of volume

• = 5.6 litres of volume.
