The empirical formula is thus N 2 O. And so this could be the likely empirical formula. Since the amount.
Since the amount.
This chemistry video tutorial explains how to find the empirical formula given the mass in grams or from the percent composition of each element in a compoun. Find the number of moles of each element in a sample of the molecule. Determine the mass of each element in a compound. To determine the empirical formula of this compound we must first calculate the masses of C H and O.
