JEE Mains · Chemistry · STD 11 - 1. Some basic concept of chemistry
Quantitative analysis of an organic compound (X) shows following % composition.
C : \(14.5 \%\)
Cl : 64.46%
H: 1.8 %
(Empirical formula mass of the compound \((\mathrm{X})\) is __________ \(\times 10^{-1}\)
(Given molar mass in \(\mathrm{g} \mathrm{mol}^{-1}\) of \(\mathrm{C}: 12, \mathrm{H}: 1, \mathrm{O}: 16, \mathrm{Cl}: 35.5\))
- A 1655
- B 1600
- C 1650
- D 1645
Answer & Solution
Correct Answer
(A) 1655
Step-by-step Solution
Detailed explanation
\(\begin{array}{ll:cccl} & \mathrm{C} & \mathrm{Cl} & \mathrm{H} & \mathrm{O} & \\ \text { %mass } & 14.5 & 64.46 & 1.8 & 19.24\end{array}\) Molar ratio \(\frac{14.5}{12} \quad \frac{64.46}{35.5} \quad \frac{1.8}{1} \quad \frac{19.24}{16}\)…
