**Concentrations Calculations (% weight/volume)**

A tutorial on calculating the concentration of a solution in % weight-volume

Example:

You dissolve 2.5 moles of strantium acetate into 1.0 L of water. Determine the concentration of the solution in %W/C.

**Concentration of Solutions: Volume/Volume % (v/v)**

A volume/volume percent (v/v) gives the volume of solute divided by the volume of the solution (expressed as a percent).

The following video looks at calculating concentration of solutions.

We will look at a sample problem dealing with volume/volume percent (v/v)%

Example:

Rubbing alcohol is commonly used as an antiseptic for small cuts. It is sold as 70% (v/v) solution of isopropyl alcohol in water. What volume of isopropyl alcohol is used to make 500 mL of rubbing alcohol?

**Concentration of Solutions: mass/volume % (m/v)% **

The following video looks at calculating concentration of solutions.

We will look at a sample problem dealing with mass/volume percent (m/v)%.

Example:

Many people use a solution of sodium phosphate (Na_{3}PO_{4} - commonly called TSP), to clean walls before putting up wallpaper. The recommended concentration is 1.7%(m/v). What mass of TSP is needed to make 2.0 L of solution?

**Concentration of Solutions: Mass/Mass % (m/m)%**

A mass/mass percent gives the mass of a solute divided by the mass of solution (expressed as a percent)

The following video looks at calculating concentration of solutions.

We will look at a sample problem dealing with mass/mass percent (m/m)%

Example:

CaCl_{2} is used to melt ice on roads. To determine how much CaCl_{2} has been used, you take a sample of slush to analyze. The sample had a mass of 23.47g. When the solution was evaporated, the residue had a mass of 4.58g. What was the mass/mass percent of CaCl_{2} in the slush? How many grams of CaCl_{2} were present in 100g of solution?
