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:
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.
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.
