## Question:

If one liter of calcium carbonate solution contains {eq}5.34 \times 10^{-3} {/eq} moles, what is the corresponding mass of calcium carbonate in a liter, and therefore the concentration in mg/L (not g/L)?

## Solute Concentration:

The concentration of a solute (dissolved substance) in a solution (homogeneous mixture), can be generally defined as the quantity of that solute that will be found in a certain unit quantity or volume of the solution. This definition is rather vague because there are several valid forms in which you can express the solute concentration. More specifically, two common forms of solute concentration are mass concentration and molar concentration (molarity). For a particular solute species these parameters are related to each other through the solute's molar mass.
