Vedclass · Answer

(D) $(i)$ Molecular mass of $CO_2$ (carbon dioxide) = (Atomic mass of carbon $	imes 1$) + (Atomic mass of oxygen $	imes 2$) = $12 + (16 	imes 2) = 12 + 32 = 44\,u$.$(ii)$ Molecular mass of $CH_4$ (methane) = (Atomic mass of carbon $	imes 1$) + (Atomic mass of hydrogen $	imes 4$) = $12 + (1 	imes 4) = 12 + 4 = 16\,u$.$(iii)$ Molecular mass of $C_2H_6$ (ethane) = (Atomic mass of carbon $	imes 2$) + (Atomic mass of hydrogen $	imes 6$) = $(12 	imes 2) + (1 	imes 6) = 24 + 6 = 30\,u$.

Calculate the molecular masses of $CO_2$,$CH_4$ and $C_2H_6$.
