The mass of the solution is given by the sum of the solute's mass and the solvent's mass:
Where:
: is the mass of the solution
: is the mass of the solute
: is the mass of the solvent
The solute is the salt (40.0 g) and the solvent is the water (100 g), so:
Therefore, the mass of the solution is 140 grams.
