Question

A compound was found to contain 5.37% nitrogen. What is the minimum molecular weight of compound ?

• A. $26.07$
• B. $2.607$
• C. $260.7$
• D. None of these

Answer 1

The correct option is C $260.7$

$5.37g$ of $N$ in $100g$ compound.

$14gN$= $\frac{100\times 14}{5.37}=260.7$ g compound

which is the minimum molecular wt as it should have at least one $N.$

Hence (c) is the correct answer.
