Question

The weight of a molecule of the compound $C_{10}{H}_{22}$ is:

• A. $1.09\times {10}^{-21}$g
• B. $2.36\times {10}^{-22}$g
• C. $5.025\times {10}^{-23}$g
• D. $16.023\times {10}^{-23}$g

Answer 1

Answer: (B)

$2.36\times {10}^{-22}$g

The weight of $N_A$ molecule of the compound $C_{10}{H}_{22}$ is $142$ g

Weight of one molecule is $\frac{142}{6.023\times {10}^{23}}=2.36\times {10}^{-22}$g.
