Question

17) Calculate the number of atoms present in
5.6 litres of a diatomic gas at NTP.
a) 6 x 1023 b) 3 x 1023
c) 6 x 1022 d) 3 x 1022​

Answer 1

Answer:

B

Explanation:

no. of atoms at ntp =find moles and no. of atoms in molecule like N2 two atoms then

moles at ntp volume / 22.4 =5.6/22.4=0.25

and it is a diatomic molecule then multiple 2

2* 0.25

and multiple avagadro number

2*0.25*6.023*1023 = 3*1023
