Zinc metal can be obtained from zinc oxide, ZnO, by reaction at high temperature with carbon monoxide,

Question:

Zinc metal can be obtained from zinc oxide, ZnO, by reaction at high temperature with carbon monoxide, CO.
ZnO(s) + CO(g) → Zn(s) + CO2(g)
The carbon monoxide is obtained from carbon.
2C(s) + O2(g) → 2CO(g)
What is the maximum amount of zinc that can be obtained from 75.0 g of zinc oxide and 50.0 g of carbon?
