Chemistry · Some Basic Concepts of Chemistry
हिन्दीAn organic compound contains \( 40\% \) carbon, \( 6.67\% \) hydrogen, and the remaining is oxygen. If its molecular mass is \( 180\text{ g mol}^{-1} \), its molecular formula is:
Correct answer · Option 3
\( \text{C}_6\text{H}_{12}\text{O}_6 \)
Explanation
Empirical formula is \( \text{CH}_2\text{O} \) with empirical mass \( 30\text{ g/mol} \). \( n = \frac{180}{30} = 6 \). Molecular formula = \( (\text{CH}_2\text{O})_6 = \text{C}_6\text{H}_{12}\text{O}_6 \).
