The empirical formula of the compound was found to be 𝐢𝐻2𝑂. If the molar mass of the compound is 150𝑔/π‘šπ‘œπ‘™. 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 = 5Γ—CH2O = C5H10O5

About Fundamental Concepts of Chemistry

Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
