What is the empirical formula of a compound with the molecular formula N_2O_4?
A
NO_4
B
N_2O
C
NO_2
D
N_2O_4
Verified step by step guidance1
Identify the molecular formula given: \(N_2O_4\).
Determine the subscripts of each element in the molecular formula: nitrogen (N) has 2 atoms, oxygen (O) has 4 atoms.
Find the greatest common divisor (GCD) of the subscripts 2 and 4, which is 2.
Divide each subscript in the molecular formula by the GCD to simplify the ratio: \(\frac{2}{2} = 1\) for nitrogen and \(\frac{4}{2} = 2\) for oxygen.
Write the empirical formula using the simplified subscripts: \(NO_2\).
