Define mole fraction, weight by weight (w/w) and parts per million as ways of expressing solution concentrations?
Ans:
Mole fraction, weight by weight (w/w) and parts per million as ways of expressing solution concentrations:
Mole fraction is the ratio of moles of a particular component to the total number of moles of solute and solvant. It is denoted by x.
Weight by weight (w/w) is solute mass per hundred grams of solution.
Parts per million (ppm) is amount of solute in one million parts of solution.
Mole fraction, weight by weight (w/w) and parts per million are other ways of expressing concentration of solutions
