A solution is defined as a homogeneous mixture. Is a small sample of air a solution? Is the atmosphere a solution?

Calculate the concentration in (w/w) of the following solutions: a. 20.0g of solute is dissolved in enough water to give 150.mL of solution. The density of the resulting solution is 1.20g/mL. b. A 10.0-mL sample with a density of 1.10g/mL leaves 1.18g of solid residue when evaporated. c. A 25.0-g sample of solution on evaporation leaves a 1.87-g residue of MgCl2.

A solution is 0.1% by mass calcium chloride. Therefore, 100. g of the solution contains g of calcium chloride.
