What equation relates mass concentration to solute mass and solution volume?

$\text{concentration} = \frac{\text{mass of solute}}{\text{volume of solution}}$

What unit is commonly used for mass concentration?

Grams per cubic decimetre, $\mathrm{g/dm^3}$ .

How can you calculate the mass of solute from the concentration and volume of a solution?

$\text{mass of solute} = \text{concentration} \times \text{volume of solution}$

How does increasing the mass of solute affect concentration if the solution volume stays the same?

The concentration increases.

How does increasing the solution volume affect concentration if the solute mass stays the same?

The concentration decreases.
