What is the sum of mole fractions of all the components in a three component system?

Explanation

To find the sum of mole fractions of all the components in a three-component system, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Mole Fraction**:
- The mole fraction (X) of a component in a mixture is defined as the ratio of the number of moles of that component to the total number of moles of all components in the mixture.
- Mathematically, for a component \(i\):
\[
