equilibrium constant for;
so3 <----> so2 + 1/2o2
is found to be 0.471M^1/2 @ 600deg C
after a quantity of sulfur trioxide is allowed to come to equilibrium in a 1L flask @ 600deg C, 0.2 mol oxygen was found to be present. What mass of sulfur trioxide was initially placed in the flask?

answer is 62.3g but i get 20.9g...?
