Vedclass · Answer

(A) Step $1$: The atomic weight of nitrogen is $14 	ext{ g/mol}$.Step $2$: For a compound to contain nitrogen, it must have at least one nitrogen atom.Step $3$: Let the molecular weight be $M$. Given that the percentage of nitrogen is $20 \%$, we have $\frac{14}{M} 	imes 100 = 20$.Step $4$: Solving for $M$: $M = \frac{14 	imes 100}{20} = 70 	ext{ g/mol}$.Step $5$: Since the compound must contain at least one nitrogen atom, the minimum molecular weight is $70 	ext{ g/mol}$.

An organic compound containing $C$, $H$, and $N$ has $20 \%$ nitrogen by mass. What is the minimum possible molecular weight of this compound?
