Molarity and Molality. Molarity (M) is defined as the number of moles of solute per liter of solution. ... When water is the solvent and the concentration of the solution is low, these differences can be negligible (d = 1.00 g/mL).
1. molarity - the number of moles of solute present in 1 litre solution at a particular temperature is called molarity .
it is represented by ' M '
2. Molality - the number of moles of solute present in 1kg solvent is called molality .
it is represented by 'm'.
3. ppm - parts per million
mass of solute by mass of solution × 10 power 6
4 . mole fraction - number of moles of each component divide by sum of number of moles of all others components...
it is denoted by X .
X = Na by Na +Nb + Nc
N - number of moles
a +b + c are components.
hope it helps you ..
