Calculate the Molecular Mass of- NH3, CO2, HCl, Cl2

Answer:

• Molecular mass of Hydrogen, carbon, oxygen, chlorine and nitrogen is 1, 12, 16, 35 and 14
• Making use of the equation calculate the number of atoms in each chemical or molecular element
• Multiply each element’s atomic weight by its number of atoms.
• Carry out the same procedure for each element in the molecule or complex.
• Add all of the results from the previous step.

Molecular mass of- NH3

=14+1×3

=17 g/mol

Molecular mass of- CO2

=12+16×2

=12+32

=44 g/mol

Molecular mass of- HCl

=1+35

=36 g/mol

Molecular mass of- Cl2

=35×2

=70 g/mol
