Question

Calculate molecular mass of C02 and C2H6​

Answer 1

Answer:

Molecular mass of CO² =

Mass of Carbon + 2 × Mass of oxygen

= 12 + 2(16) = 12 + 32 = 44

Similarly ,

Molecular mass of C²H⁶ = 2(12)+6(1)

= 24 + 6 = 30

Explanation:

Hope it helps !!

Answer 2

Explanation:

Molecular mass of CO2=12+2×(16)

=12+32

=44

Molecular mass of C2H6=(12×2)+(1×6)

=24+6

=30
