One mole of a gas filled in a container at N.T.P., the number of molec

1.	One mole of a gas filled in a container at N.T.P., the number of molecules in 1 cm3 of volume will be(a) 6.02 x 1023/22400(b) 6.02 x 1023(c) 1/22400(d) 6.02 x 1023/76
Answer» Correct Option (a) 6.02 x 10²³/22400 Explanation: Number of molecule in 22.4 litre gas at N.T.P. 6.023 x 10²³ or number of molecule in 22.4 x 10³cm³ = 6.023 x 10²³ [As 22.4 litre = 22.4 x 10³ cm³] :. Number of molecules in 1 cm³ = 6.023 x 10²³/22400

One mole of a gas filled in a container at N.T.P., the number of molecules in 1 cm3 of volume will be(a) 6.02 x 1023/22400(b) 6.02 x 1023(c) 1/22400(d) 6.02 x 1023/76

Answer»

Correct Option (a) 6.02 x 10²³/22400

Explanation:

Number of molecule in 22.4 litre gas at N.T.P. 6.023 x 10²³

or number of molecule in 22.4 x 10³cm³ = 6.023 x 10²³ [As 22.4 litre = 22.4 x 10³ cm³]

:. Number of molecules in 1 cm³ = 6.023 x 10²³/22400
