What is the mole fraction of CO2 if one liter of a mixture contains 2.50mol O2,5.00 mol N2, and 1.50 mol CO2?
A).214
B).167
C)5.67
molefractionCO2= molesCO2/totalmoles
To find the mole fraction of CO2 in the mixture, you need to divide the moles of CO2 by the total moles of all the components in the mixture.
First, calculate the total moles of all the components in the mixture:
Total moles = moles of O2 + moles of N2 + moles of CO2
= 2.50 mol + 5.00 mol + 1.50 mol
= 9.00 mol
Now, calculate the mole fraction of CO2:
Mole fraction of CO2 = moles of CO2 / total moles
= 1.50 mol / 9.00 mol
≈ 0.167
Therefore, the mole fraction of CO2 in the mixture is approximately 0.167.
The correct answer is B) 0.167.
