Define the following term mole fraction
WebMole fraction is a unit of concentration, defined to be equal to the number of moles of a component divided by the total number of moles of a solution. Because it is a ratio, mole fraction is a unitless expression. The mole fraction of all components of a solution, … Mass Fraction (kg/kg or parts per) - mass of one fraction (could be multiple … It gives the smallest whole number ratio of elements in a compound using … Raoult's Law is expressed by the vapor pressure equation: P solution = Χ … WebThe mole fraction of gas A is often given the symbol x A. The mole fraction of gas B would be x B - and so on. Pretty obvious really! For example, in a mixture of 1 mole of nitrogen and 3 moles of hydrogen, there are a total of 4 moles of gas. The mole fraction of nitrogen is 1/4 (0.25) and of hydrogen is 3/4 (0.75). Partial pressure
