हिन्दीCalculate the concentration of nitric acid in moles per litre in a sample which has a density, \( 1.41\text{ g mL}^{-1} \) and the mass per cent of nitric acid in it being \( 69\% \).
Correct answer · Option 1
15.43 mol L⁻¹
Explanation
Mass of \( \text{HNO}_3 \) in 1 L = \( 1410 \times 0.69 = 972.9\text{ g} \). Molarity = \( \frac{972.9}{63} = 15.43\text{ mol L}^{-1} \).
