Q7 / 54 · JEE Advanced 2022 (Paper 1) · Chemistry

The weight percentage of hydrogen in $Q$ , formed in the following reaction sequence, is
[Given: Atomic mass of $H = 1, C = 12, N = 14, O = 16, S = 32, Cl = 35$ ]

Correct answer: 1.31

Solution

Formula of compound $= C_{6} H_{3} N_{3} O_{7}$
Molar Mass of compound $= (12 \times 6 + 3 + 14 \times 3 + 16 \times 7) g$
$= 229 g$
Weight $%$ of $H = \frac{3}{229} \times 100 = 1.31$

Hence, the correct answer is 1.31.
