What is the molecular formula of a compound if its empirical formula is #CFBrO# and its molar mass is 381.01 g/mol?
Molar mass of compound (
Now you need to calculate the molar mass of
The molar mass of:
The molar mass of empirical formula, therefore (
In order to get the molecular formula of
divide molar mass of compound by molar mass of empirical formula, like this:
Rounded to nearest whole number
Now, multiply the whole number by the Empirical Formula.
Therefore your molecular formula is
