Question

A large organic molecule has a mass of $\mathbf{1}\mathbf{.}\mathbf{41}\mathbf{\times }{\mathbf{10}}^{\mathbf{-}\mathbf{21}}\mathbf{}\mathbf{kg}$. What is the molar mass of this compound?

Short answer

The Molar Mass of the compound is$8.49\times {10}^{2}kg/mol$

Step-by-step solution

Step :1

Mass of organic molecule$m=1.14\times {10}^{-21}kg$

The molecular mass is$M=N_A\times m$, here $N_A$is Avogadro Number

Putting all the values

$$\begin{gathered} M=N_A\times m \\ =6.022\times {10}^{23}\times 1.41\times {10}^{-21} \\ =8.49\times {10}^{2}kg/mol \end{gathered}$$

The Molar Mass of the compound is $8.49\times {10}^{2}kg/mol$.
