Solution Concentrations

These flashcards cover key concepts and definitions related to solution concentrations, important for understanding how to calculate and express concentration in various forms.

Solution Concentration

The amount of solute present in a given volume of solution, expressed in various units.

Mass Percent (m/m)

The concentration by mass of solute in a solution, expressed as grams of solute per 100 grams of solution.

Volume Percent (v/v)

The concentration by volume of solute in a solution, expressed as milliliters of solute per 100 milliliters of solution.

Mass/Volume Percent (m/v)

The concentration of solute expressed as grams of solute per 100 milliliters of solution.

Molarity (M)

The number of moles of solute per liter of solution, expressed as moles/liter.

Mass Percent Formula

Mass percent (m/m) = (mass of solute / total mass of solution) × 100%.

Volume Percent Formula

Volume percent (v/v) = (volume of solute / total volume of solution) × 100%.

Mass/Volume Percent Formula

Mass/Volume percent (m/v) = (grams of solute / volume of solution in mL) × 100%.

Example Calculation of Mass Percent

To find the mass percent of KCl in a solution, calculate (grams of KCl / total grams of solution) × 100%.

Molarity Calculation

Molarity is calculated by dividing the moles of solute by the volume of the solution in liters.
