i have difficulty in this question. any help would be much appreciated.

1)CO(g)+2H2(g)->CH3OH(g)
at 225c, K is 10.2 liter^2/mol^2. what concentration of CH3OH(g)is in equilibrium with CO(g) at a concentration of 0.020 mol/liter and H2(g) at a concentration of 0.020mol/liter?

K(eq) = [CH3OH] / [CO][H2]^2

let [CH3OH] = [x]
Substituting,
10.2 = [x] / [0.02][0.02]^2
Solve for [x]
