Hi!! I am given the following exercise and I really don’t know how to do it. It says: “At a pressure of 1.50x10^5, 1.00 mol of sulfur dioxide gas, SO2, was mixed with 1.00 mol of oxygen gas, O2. The final equilibrium mixture formed was found to contain 0.505 mol of O2.
2SO2(g) + O2(g) < ———-> 2SO3 (g)
Calculate the amount in mol of SO2 and SO3 in the equilibrium mixture”can someone explain me how to do it please?
