The empirical formula and molecular mass of a compound are CH2O and 180 g respectively. What will be the molecular formula of the compound? (i) C9H18O9 (ii) CH2O (iii) C6H12O6 (iv) C2H4O2

Correct Answer: (iii) C₆H₁₂O₆

Explanation:

Given,

Molar mass of Carbon=12

Molar mass of Hydrogen=1

Molar mass of Oxygen=16

So,

The molecular weight of compound is 6 and so the molecular formula of this compound would be C₆H₁₂O₆
