Chem question, need help please?

For the reaction 2NO2(g) ì N2O4(g) at 325 K equilibrium is established when [N2O4] = 0.020M and [NO2] = 1.08 ´ 10- 2M. What is the equilibrium constant for this reaction?

5.8 x 10^-3
2.9 x 10^-1
5.4 x 10^-1
1.7 x 10^2

K = [N2O4]/[NO2]^2

K = 0.02/(1.08 x 10^-2)^-2

K = 1.7 x 10^2
