Question

)Calculate the numbers of molecules in,
28 gm of N2 gas

Answer 1

Answer:

1 Nitrogen mole or 28 grams of nitrogen contains 6.023×10^23 number of molecules.

Answer 2

Explanation:

Mass of N₂ = 28g

Mass of one mole of N₂ = 28g

Number of moles = mass of substance /mass of one mole

                              = 28/28

                               = 1 mole

Therefore in 28g of N₂ gas 1 mole of molecules are present.
