## Question:

A solution was prepared by dissolving 1 gram of {eq}NH_3 {/eq} in 250 grams of water. The density of the resulting solution was 0.974 g/mL. Determine the mole fraction of {eq}NH_3 {/eq} in the solution.

## Mole fraction:

Mole fraction is the fraction of a chemical species in a mixture in terms of moles. It can be used to determine the partial pressure of the gas in a mixture. It can also be used to determine the pressure of a system given the mole fractions of the components with their respective vapor pressure at pure state.
