Question

The empirical formula for glucose is CH2). The molar mass of glucose is 180.2 grams per mole. Determine the molecular formula of glucose.

Answer 1

find the total mr of CH2. take the new mr/180.2.

take the answer ratio times CH2 respectively

Answer 2

Answer:

6 CH2O which is C₆H₁₂O₆

Explanation:

The empirical formula for glucose is CH2). The molar mass of glucose is 180.2 grams per mole. Determine the molecular formula of glucose.

Formula: C₆H₁₂O₆

Empirical Formula is CH2O

Molecular Molar Mass is 180.20g/mole

Empirical Molar Mass is 30.02 g/mole

molecular formula of glucose is C₆H₁₂O₆

n = 180.20/30.02=6

n×(CH2O)

where n = molecular molar mass / empirical molar mass

So we end up with 6 CH2O which is C₆H₁₂O₆
