Calculate Moles from Mole Fraction



Formula

The formula to calculate the moles of a component (n_c) from the mole fraction (x_c) and total moles (n_t) is:

\[ n_c = x_c \cdot n_t \]

Where:

Mole Fraction Definition

The mole fraction is a way of expressing the concentration of a component in a mixture. It is defined as the ratio of the number of moles of the component to the total number of moles of all components in the mixture. The mole fraction is a dimensionless quantity and is often used in chemistry to describe the composition of mixtures. It is particularly useful in calculations involving gases and solutions.

Example Calculation

Let's assume the following values:

Using the formula to calculate the moles of the component (n_c):

\[ n_c = 0.2 \cdot 100 = 20 \]

The moles of the component (n_c) is 20 moles.
