Question

Determine the solution mass if you dissolve 3.020 g of salt in 100.0 mL of water. The density of water is 1.00 g/mL. Report with correct significant figures.

Answer 1

The mass of the solution is obtained as 103.02 g.

A solution is a homogeneous mixture of two or more substances, where one substance (solute) is dissolved in another substance (solvent).

If the solute is a solid, it dissolves in the solvent. The solute particles become surrounded by solvent molecules, breaking down into smaller particles until they are uniformly distributed throughout the solvent.

Density of water = 1.00 g/mL

Mass of water = 100.0 mL * 1.00 g/mL

= 100 g

Mass of the solution = Mass of solute + Mass of solvent

= 100 g + 3.020 g

= 103.02 g
