हिन्दीCalculate the molarity or density conversion: If a solution has a density of \( 1.25 \text{ g cm}^{-3} \), what is its equivalent value in \( \text{kg m}^{-3} \)?
Correct answer · Option 4
\( 1.25 \times 10^3 \text{ kg m}^{-3} \)
Explanation
\( 1 \text{ g cm}^{-3} = \frac{10^{-3} \text{ kg}}{(10^{-2} \text{ m})^3} = 10^3 \text{ kg m}^{-3} \). Hence \( 1.25 \text{ g cm}^{-3} = 1.25 \times 10^3 \text{ kg m}^{-3} \).
