ANSWER
The mass of solid iron formed is 78.93 grams
Step-by-step explanation
Given that;
The mass of Fe2O3 is 188g
The mass of CO reacted is 59.5g
Follow the steps below to find the mass of Fe reacted
Step 1; Write the balanced equation for the reaction
Step 2; Find the number of moles of each reactant
Recall, the molar mass of Fe2O3 is 159.69 g/mol and the molar mass of CO is 28.01 g/mol
The mole of Fe2O3 is 1.18 moles and the mole of CO is 2.12 moles
Hence, the limitig reagent of the reaction is CO
Step 3; Find the mole of Fe using stoichiometry ratio
Let x represents the number of moles of Fe
Therefore, the number of moles of Fe is 1.41 moles
Step 4; Find the mass of Fe
The molar mass of Fe is 55.845u
Therefore, the mass of solid iron formed is 78.93 grams
