Question

Solution A: 45 solute particles and 90 solvent particles. Solution B: 90 solute particles and 180 solvent particles. Calculate the solute concentration and solvent concentration for each solution. Show your work.

Answer 1

Solution A:

No. of solute particles: 45

No. of solvent particles:90

Solute concentration = Amount of solute/total volume of solution X 100

= 45/135 x100

=33.3 %

solvent concentration=Amount of solute/total volume of solution X 100

=90/135 x100

= 66.6%

Solution B:

No. of solute particles: 90

No. of solvent particles:180

solute concentration = Amount of solute/total volume of solution X 100

= 90/270 x100

=33.3 %

solvent concentration=Amount of solute/total volume of solution X 100

=180/270x100

= 66.6%
