Answer 1

Heyy mate ❤✌✌❤

Here's your Answer...

⤵️⤵️⤵️⤵️⤵️⤵️

Molar Mass of N2 is 28.

Therefore, Molar Mass of 5 mole of N2= 5 × 28

= 140.
✔✔✔

Answer 2

Molecular weight of N2

gram Atomic weight of N is 14 g.

gram Molecular weight = 14 g×2

                              = 28 g

Mole concepts

1 mole of gas always occupies 1 gram molecular weight .

Application of the concept

1 mole will occupy 28 g

5 moles will occupy 28 g × 5

                          = 140 g

The mass of the gas is 140 g.

Hope it helps you
