Vedclass · Answer

(A) The molar mass of methane $(CH_4)$ is calculated as: $12 + (4 	imes 1) = 16 \ g/mol$. According to the mole concept,$1 \ mol$ of $CH_4$ contains $6.022 	imes 10^{23}$ molecules,which weighs $16 \ g$. Therefore,the weight of one molecule of $CH_4$ is: $\frac{16}{6.022 	imes 10^{23}} \ g$. Calculation: $16 \div 6.022 \approx 2.657$. Thus,the weight is $2.657 	imes 10^{-23} \ g$.
