Question

Calculate the volume occupied by 4.2 g of nitrogen at STP

Answer 1

Answer:

To find the moles of nitrogen, it is necessary to use the idea of molar volume

Mass of N2 = 1.4 g

Moles of N2 = 1.4g / 28g per mole = 0.05 moles

One mole of N2 at S.T.P has volume = 22.414 dm3

0.05 moles of N2 at S.T.P has volume = 22.414 × 0.05 = 1.12 dm 3

Answer 2

Answer:

3.36liters

Explanation:

As frist cal. The no. Of moles then multiply with 22.4 you will got your answer
