Answer:
Molecular formula = C₄H₆O₂
Explanation:
Given data:
Empirical formula of butanedion = C₂H₃O
Molar mass of butanedion = 86.09 g/mol
Molecular formula butanedion = ?
Solution:
Formula:
Molecular formula = n(empirical formula)
n = molar mass of compound / empirical formula mass
empirical formula mass = 2×12 +1.008×3 +1×16 = 43.024
n = 86.09 / 43.024
n = 2
Molecular formula = n (empirical formula)
Molecular formula = 2 (C₂H₃O)
Molecular formula = C₄H₆O₂
