Can you help me solve this question in detail?

Use Hess's law to calculate the standard heat of the warer-gas shift reaction CO(g)+H2O(v)CO2(g)+H2(g) from each of the two sets of data given here. (a) CO(g)+H2O(l)CO2(g)+H2(g); H^r0=+1226Btu/b-mole H2O(i)H2O(v):Hc=+18.935Btu/b-mole (h) CO(g)+21O2(g)CO2(g):A^i=121,740Btu/b-mole H2(g)+21O2(g)H2O(v):H^r=104,040 Btulb-mole
