Answer: -

280mg

Explanation: -

The chemical formula is C14H18N2O5

Molar mass of the compound = 12 x 14 + 1 x 18 + 14 x 2 + 16 x 5 = 294 gram

Number of nitrogen atoms present in the formula = 2

Mass of nitrogen present= 14 x 2 = 28 gram

Thus 294 gram of the compound has 28 gram.

Hence 2.95grams of the compound has (28 gram x 2.95 gram / 294 gram)

= 0.28 gram

= 280 mg

Thus 280 mg of nitrogen is present in 2.95 grams of C14H18N2O5
