What is the molecular formula ofan unknown substance it its empirical formula is C7H2O5 and its molar mass is 176.12 g/mol?

Sagot :

COSMIC23GO

Answer:

Molecular Formula = C7H2O5

Same also as the empirical formula :)

Explanation:

Mass of elements × subscript

C= 12×7 = 84

H= 1×2 = 2

O= 16×5 = 80

_______

Total= 166 g/mol

Molar mass ÷ Total mass

176.12÷166= 1

(C7H2O5) × 1 = C7H2O5
