हिन्दीThe density of a liquid is \( 1.25\text{ g}\cdot\text{cm}^{-3} \). What is its value in the SI unit of density (\( \text{kg}\cdot\text{m}^{-3} \))?
Correct answer · Option 2
\( 1250\text{ kg}\cdot\text{m}^{-3} \)
Explanation
Convert units: \( 1\text{ g}\cdot\text{cm}^{-3} = \frac{10^{-3}\text{ kg}}{(10^{-2}\text{ m})^3} = 10^3\text{ kg}\cdot\text{m}^{-3} \). Thus, \( 1.25 \times 10^3 = 1250\text{ kg}\cdot\text{m}^{-3} \).
