Based on pressure values for each component of the reaction, what is the value of the reaction quotient, Q?

Equation: C2H2 + 2 H2 -> C2H6

C2H2 has a pressure of 5.05 atm
H2 has a pressure of 4.35 atm
C2H6 has a pressure of 0.0225 atm

Reaction quotient is defined as
Q = p(C2H6)/p(C2H2)*p(H2)^2
where p(C2H6) means the partial pressure of C2H6, p(C2H2) means partial pressure of C2H2) etc.
Now just plug in the values listed and calculate Q.
