हिन्दीWhat is the concentration of sugar (\( \text{C}_{12}\text{H}_{22}\text{O}_{11} \)) in \( \text{mol L}^{-1} \) if its \( 20\text{ g} \) are dissolved in enough water to make a final volume up to \( 2\text{ L} \)?

Correct answer · Option D
0.0292 mol L⁻¹
Explanation
Molar mass of sugar = \( 342\text{ g mol}^{-1} \). Moles = \( \frac{20}{342} = 0.0585\text{ mol} \). Molarity = \( \frac{0.0585}{2} = 0.0292\text{ mol L}^{-1} \).
