Answer:
Molecular formula = H₂S₂O₈
Explanation:
Given data:
Empirical formula = HSO₄
Formula mass = 194.13 amu
Molecular mass = ?
Solution:
Molecular formula = n × empirical formula
n = molar mass of the compound / empirical formula mass
Empirical formula mass = 1.008 + 32.065 + 16× 4
Empirical formula mass = 97.073
n = 194.13 / 97.073
n= 2
Molecular formula = n × empirical formula
Molecular formula = 2 (HSO₄)
Molecular formula = H₂S₂O₈
