We gots......approx. $700 \cdot m g$ with respect to nitrogen......

#### Explanation:

We gots $\frac{2.50 \cdot g}{194.19 \cdot g \cdot m o {l}^{-} 1} = 0.0129 \cdot m o l$ with respect to caffeine. And thus there are $4 \times 0.0129 \cdot m o l \times 14.01 \cdot g \cdot m o {l}^{-} 1$ with respect to nitrogen, i.e. approx. $0.7 \cdot g$
