Calculating Mole Fraction
Mole fraction is a way to express the concentration of a component in a mixture. It is defined as the ratio of the number of moles of a component to the total number of moles in the mixture. Here is how you can calculate mole fraction:

Step 1: Determine the number of moles of each component
- Calculate the number of moles of each component in the mixture using the given mass and molar mass of the substance. This can be done by dividing the mass of the substance by its molar mass.

Step 2: Calculate the total number of moles in the mixture
- Add up the number of moles of all the components in the mixture to get the total number of moles in the mixture.

Step 3: Calculate the mole fraction of a component
- Once you have determined the number of moles of each component and the total number of moles in the mixture, you can calculate the mole fraction of a specific component by dividing the number of moles of that component by the total number of moles in the mixture.

Step 4: Express the mole fraction
- The mole fraction is expressed as a decimal number between 0 and 1. It represents the proportion of that component in the mixture.
By following these steps, you can calculate the mole fraction of a component in a mixture, which helps in understanding the composition and concentration of the substances present.
