What is the difference between mole fraction and mass fraction?

Mole Fraction vs Mass Fraction Mole fraction is the ratio between the moles of a constituent and the sum of moles of all constituents in a mixture. Mass fraction is the ratio between the mass of a constituent and the total mass of a mixture.

What is mole ppm?

Molarity and parts per million (ppm) are two units of measurement used to describe the concentration of a chemical solution. One mole is equivalent to the molecular or atomic mass of the solute. Parts per million, of course, refers to the number of molecules of solute per million parts of a solution.

Is mole fraction and volume fraction the same?

For ideal gases, the mole fractions are the same as the volume fractions. The molar volumes of all gases are known to be the same when they are measured at the same temperature and pressure.

Is mole fraction and solubility same?

When Pressure is Constant It means if the value of Henry’s law constant decreases, the value of mole fraction of gas in liquid increases. Mole fraction of the gas in liquid can be taken as solubility. Thus, as henry’s law constant decreases, solubility of the solute in solution increases.

How do you calculate ppm from molarity?

If you take molarity (with units mol/L), and multiply it by the molar mass (with units g/mol), you get g/L. Just multiply g/L by 1000 to convert g to mg, and you have ppm (in mg/L of water).

What is the relation between ppm and molarity?

How do you Convert from Molarity (M) to Parts Per Million (ppm) and mg/L?

Molarity (moles/Liter = M)	grams/L (g/L)	Parts Per Million (ppm)
1 M	35.5	35,500
10-1 M	3.55	3,550
10-2 M	0.355	355.0
10-3 M	0.0355	35.5
