JEE Mains · Chemistry · STD 11 - 1. Some basic concept of chemistry
0.01 mole of an organic compound \((X)\) containing \(10 \%\) hydrogen, on complete combustion produced \(0.9 \mathrm{~g} \mathrm{H}_2 \mathrm{O}\). Molar mass of \((\mathrm{X})\) is _____ \(\mathrm{g} \mathrm{mol}^{-1}\).
- A 200
- B 320
- C 100
- D 150
Answer & Solution
Correct Answer
(C) 100
Step-by-step Solution
Detailed explanation
Organic compound \(\xrightarrow{\text { combustion }} \underset{\substack{\mathrm{0.9} \mathrm{gm}}}{\mathrm{H}_2 \mathrm{O}}\) \(\therefore\) mole of \(\mathrm{H}_2 \mathrm{O}=\frac{0.9}{18}=0.05 \mathrm{~mole}\) \(\therefore\) mole of H in…
