Question

Aspartame, an artificial sweetener contains $9.52$ weight per nitrogen. There are two nitrogen atoms per molecule. The molecular weight of aspartame is:

• A. 147
• B. 294
• C. 588
• D. 266

Answer 1

Answer: (B)

294

The weight of $2$ nitrogen atoms is $2\times 14=28g$.
$100$ g of aspartame contains $9.52$ g of nitrogen.
Thus, the molecular weight of nitrogen is $\frac{100}{9.52}\times 28=294$.
