The empirical formula of the compound was found to be πΆπ»2π. If the molar mass of the compound is 150π/πππ. The molecular formula of the compound is:
Correct answer: D. C5H10O5
- A. C6H12O6
- B. C4H8O2
- C. C5H10O4
- D. C5H10O5
Explanation
The molecular formula is given byMolecular formula = n x empirical formulaWhere n= molecular formula mass/empirical formula massThe empirical formula mass of CH2O is =12+2+16=30g/mol.n = 150/30=5. So Molecular formula is Molecular formula = 5ΓCH2O = C5H10O5
