Calculate the reduced mass of a nitrogen molecule in which both nitrogen atoms have an atomic mass of 14.00. Do the same for a hydrogen chloride molecule in which the chlorine atom has an atomic mass of34.97. Hydrogen has an atomic mass of 1.008.

Explanation:

To calculate the reduced mass of nitrogen molecule = Mn x Mn/ Mn + Mn

Mn = atomic mass of Nitrogen =  14.00

reduced mass = 14 x 14 /14 + 14 = 7

Similarly for HCl; reduced mass for a hydrogen chloride molecule = Mh x Mcl/Mh + Mcl

where Mh = atomic mass of hydrogen = 1.008

Mcl = atomic mass of chrorine = 34.97

reduced mass for HCl = 1.008 x 34.97 /1.008 + 34.97

= 0.97
