Dilutions, Solutions, and Concentrations

Total Volume Equation - (parts concentrate) + (parts diluent) = (total volume)

Final Concentration - (original concentration) x (dilution) = (final concentration)

Dilution Problem Formula - V1C1 = V2C2

Percent Weight per unit weight - (unit weights of solute)/(100 unit weights of solution)

Percent Volume per unit volume - (mL concentrate)/(100 mL solution)

Percent Weights per unit volume - (g solute)/(100 mL solution)

the mass of 1 liter of water is equal to 1 kg at 4 degrees Celsius

one should read the calibration at the bottom of the meniscus when measuring the level of a liquid medication
