What is the empirical formula of ?
A

C
D
Verified step by step guidance1
Identify the number of atoms of each element in the given molecular formulas. For example, in \( \mathrm{N_2O_4} \), there are 2 nitrogen atoms and 4 oxygen atoms.
Write the ratio of the atoms of each element. For \( \mathrm{N_2O_4} \), the ratio of nitrogen to oxygen is 2:4.
Simplify the ratio to the smallest whole numbers by dividing both numbers by their greatest common divisor. For 2:4, divide both by 2 to get 1:2.
Express the empirical formula using the simplified ratio. For the example, the empirical formula is \( \mathrm{NO_2} \).
Repeat the process for any other given formulas to confirm their empirical formulas by simplifying their atomic ratios.
