Answer:

Molecular mass:The sum of the atomic mass of all the atoms in a molecule is known as atomic mass.

To calculate :The molecular or molar mass of i)NHOH ii)NaCo

i)NHOH

The element composition of NHOH is:

Nitrogen-14. 0067

Hydrogen-1. 00794

Oxygen-15. 9994

M. Mass=(14. 0067+1. 00794+15. 9994)

= 31. 01404

ii)NaCo

The element composition of NaCO is :

Sodium-22. 98976

Carbon-12. 0107

Oxygen-15. 9994

M. Mass=(22. 98976+12. 0107+15. 9994

= 50. 99986
