Answer :
The mole fraction of a substance in a mixture is the ratio of the number of moles of that substance to the total number of moles of all substances in the mixture.
converting the masses of CO2 and O2 into moles:
CO2: 26.1 g ÷ 44.01 g/mol = 0.59 moles
O2: 36.6 g ÷ 32.00 g/mol = 1.14 moles
adding up the total number of moles:
0.59 moles + 1.14 moles = 1.73 moles
dividing the number of moles of O2 by the total number of moles:
1.14 moles ÷ 1.73 moles = 0.66 or 66%
So the mole fraction of O2 in this mixture is 0.66 or 66%.
What is a mixture?
In chemistry, a mixture is a concoction of two or more compounds, each of which maintains its unique chemical identity and properties. Physical separation of the components in a mixture is possible using techniques like distillation, evaporation, or filtering. The qualities of a mixture, as opposed to a chemical compound, rely on the ratios of the constituent parts. Mixtures include things like air, salt water, and gasoline.
A substance made up of two or more separate chemical compounds that are not chemically linked is referred to as a mixture. When two or more substances are physically combined, their identities are maintained, and the mixture takes the shape of solutions, suspensions, or colloids.
