What is the answer to the question mark? please show step by step solutions. thanks.

100 tons of liquid steel (at 1600C ) has been deoxidized. Al-O equilibrium curve just after deoxidation is shown above. Calculate the final oxygen content of the steel. Data for 1600C : 2Al(%)+3O(%)=Al2O3(s)G=1202050+386.3T(J) Assumptions: Assume all activity coefficients as unity. Atomic weights: Al: 27, O: 16, R=8.314J/(K.mole)
