The weight percentage of hydrogen in QQ, formed in the following reaction sequence, is

The weight percentage of hydrogen in Q , formed in the following reaction sequence, is [Given: Atomic mass of H = 1, C

[Given: Atomic mass of H=1,C=12,N=14,O=16,S=32,Cl=35H = 1, C = 12, N = 14, O = 16, S = 32, Cl = 35]

Correct answer

1.31

Step-by-step solution

The weight percentage of hydrogen in Q , formed in the following reaction sequence, is [Given: Atomic mass of H = 1, C

Formula of compound =C6H3N3O7= {C}_{6}{H}_{3}{N}_{3}{O}_{7}

Molar Mass of compound =(12×6+3+14×3+16×7)g= \left(12 \times 6 + 3 + 14 \times 3 + 16 \times 7\right)g

=229g= 229g

Weight % of H=3229×100=1.31H = \dfrac{3}{229} \times 100 = 1 . 31
