The empirical formula of a compound is determined to be ch2o, and its molecular mass is found to be 90.087 g/mol. determine the molecular formula of the compound, showing your solution.

The empirical formula of a compound is determined to be CH2O, and its molecular mass is found to be 90.087 g/mol. Determine the molecular formula of the compound, showing your solution.

This is actually quite simple, first we have to calculate the molar mass of empirical unit. Therefore we have 12+2*1+16 = 30. Then we solve 90/30 = 3. Finally we end up with 3*(CH2O) --> C3H6O3.

I hope it helps, Regards.

In order to do that, we first have to calculate the "molar mass" of empirical unit

12+2*1+16 = 30

so 90/30 = 3

so you have 3*(CH2O) --> C3H6O3

hope this helps
