हिन्दीA sample of gas occupies a volume of \( 4.5\text{ dm}^3 \). What is this volume expressed in the SI unit of volume (\( \text{m}^3 \))?
Correct answer · Option 1
\( 4.5 \times 10^{-3}\text{ m}^3 \)
Explanation
Since \( 1\text{ dm} = 10^{-1}\text{ m} \), \( 1\text{ dm}^3 = (10^{-1}\text{ m})^3 = 10^{-3}\text{ m}^3 \). Thus, \( 4.5\text{ dm}^3 = 4.5 \times 10^{-3}\text{ m}^3 \).
