Question

0.132 g of an organic compound gave 50 ml of N2 at NTP .the weight percentage of nitrogen in the compound is close to

Answer 1

Answer:

The percentage of Nitrogen in the compound is close to 47%

Explanation:

At NTP, the volume of 1 mole of gas = 22.4 litres

Using No. of moles = weight in gram/ molecular weight

Molecular weight of N₂ = 28

∴ weight of one mole of N₂ = 28 gm

∵ 22.4 litres of N₂ has weight = 28 gm

∴ 1 litre of N₂ has weight = 28/22.4 gm

or 1000 ml of N₂ has weight = 28/22.4 gm

⇒ 1 ml of N₂ has weight = 28/(22.4× 1000) gm

⇒ 50 ml of N₂ has weight = (28 × 50)/(22.4× 1000) gm

                                           = 0.0625 gm

Percentage of Nitrogen in the compound = (0.0625/0.132) × 100

                                                                     = 47.35%
