The molality that LiCl solution is
The quantity of substance in any mixture is termed as its concentration. Few of the most commonly used concentration terms are as follows:
1. Molarity (M)
2. Molality (m)
3. Mole fraction (x)
4. Components per million (ppm)
5. Massive percent ((w/w) %)
6. Volume percent ((v/v) %)
The relation between the molality and the mole fraction of the equipment is together follows:
m is the molality of solution.
You are watching: A solution of licl in water has xlicl = 0.0900. what is the molality?
is the mole portion of solvent.
is the mole portion of solute.
is the molar fixed of solvent.
The expression the relates the mole portion of solute and also solvent is,
Rearrange equation (2) to calculate .
Substitute 0.0900 because that in equation (3).
Substitute 0.0900 for , 0.91 because that and also 18 g/mol for in equation (1) to calculation the molality the LiCl solution.
Therefore molality of LiCl systems is 5.4945 m.
