¨ The empirical formula of the compound is CH2, which represents the simplest whole-number ratio of carbon and hydrogen atoms in the compound. To determine the molecular formula, we need to know the molar mass of the compound.
¨ The molar mass of the empirical formula CH2 is:
¨ (1 × 12.01 g/mol) + (2 × 1.01 g/mol) = 14.03 g/mol
¨ The given molar mass of the compound is 56 g/mol, which is exactly four times the molar mass of the empirical formula. This means that the molecular formula of the compound must be four times the empirical formula.
¨ The molecular formula of the compound can be found by multiplying the subscripts in the empirical formula by 4: So, CH2 × 4 = C4H8
¨ Therefore, the molecular formula of the compound is (C) C4H8
