The density of nitric acid solution is \(1.5 \mathrm{~g} \mathrm{~mL}^{-1}\). Its weight percentage is 68 . What is the approximate concentration (in \(\left.\mathrm{mol} \mathrm{L}^{-1}\right)\) of nitric acid? \((\mathrm{N}=14 u ; \mathrm{O}=16 u ; \mathrm{H}=1 u)\)
- A \(14.2\)
- B \(11.6\)
- C \(18.2\)
- D \(16.2\)
Answer & Solution
Correct Answer
(D) \(16.2\)
Step-by-step Solution
Detailed explanation
\begin{aligned} & \text { Given }- \text { Density }(\delta)=1.5 \mathrm{~g} / \mathrm{ml} \\ & \text { Volume }(\mathrm{v})=1000 \mathrm{ml} \\ & \text { Weight percentage }=68 \\ & \text { Mass of solution }=\text { density } \times \text { volume } \\ & 1.5 \mathrm{~g} /…
