A. How many tons of coke are needed per week to produce 8.51×104 of pig iron from a modern blast furnace using hematite? Assume that coke is pure carbon, pig iron is pure iron, and all reactions have 100 yield.
Express your answer numerically in tons.
B. How many tons of slag are produced by a modern blast furnace using 2.55×104 of limestone, ? Assume that slag is pure calcium silicate () and that all reactions go to completion.
