The composition of the stack gas are :
= 0.8713
= 0.0202
CO = 0.107
<h3 /><h3>What is a mole fraction?</h3>The ratio of the number of moles of one component of a solution or other mixture to the total number of moles representing all of the components.
Assuming 100 g of the stack gas. Calculate the mass of each species in this sample according to their percentages.
Mass of : 70% of 100 g = 70 g
Mass of : 15% of 100 g = 15 g
Mass of CO : 15% of 100 g = 15 g
Now calculate the number of moles of each species:
Number of moles of :
= 4.3 mole
Number of moles of :
= 0.10 mole
Mass of CO : = 0.53 mole
Now to calculate the mole fraction of each we use the formula:
Mole fraction of :
= 0.8713
Mole fraction of :
= 0.0202
Mole fraction of CO : = 0.107
Hence, composition of the stack gas are:
= 0.8713
= 0.0202
CO = 0.107
