Interpretation:
The volume of CO gas required and CO2 gas produced at STP should be calculated.
Concept Introduction:
According to ideal gas equation:
Here, P is pressure, V is volume, n is number of moles, R is Universal gas constant and T is temperature.
The value of Universal gas constant can be taken as
Mass of gas can be calculated from number of moles and molar mass as follows:
Here, n is number of moles, m is mass and M is molar mass.
Given Information:
The mass of Fe is 1.45 kg.
Calculation:
The balanced chemical reaction is as follows:
To calculate the volume of CO and CO2 gas number of moles of Fe, CO and CO2 should be calculated.
Molar mass of Fe is 55.845 g/mol thus,
From the balanced chemical reaction, 1 mole of FeO reacts with 1 mol of CO to produced 1 mol of Fe (s) and 1 mol of CO2 thus, number of moles of CO and CO2 will be 25
