Answer to Question #166516 in General Chemistry for Teeeeeeeeera

Question

Fe2O3 (s) + 3 CO (g) ----> 2Fe (s) + 3CO2 (g)

How many grams of CO are required to produce 25.1 mol of Fe?

m(CO)=.........g

please with steps

Answer 1

Fe2O3 +3CO --> 2Fe + 3CO2

2 mol Fe will be formed when 3 mol CO is used according to balanced equation

To produce 25.1 mol Fe there must be  

3 mol CO/2 mol Fe * 25.1 mol Fe 

mass of CO needed 

=3 mol CO/2 mol Fe * 25.1 mol Fe * 28.01 g/mol CO

=468.7 g

Answer

mass of CO needed = 469 g
