Concentrations of solute in solvent, whether in saturated solutions or not, can be expressed in many ways (molarity, molality, ppm, percent by mass, etc.). Molarity = moles of solute / liter of solution molality = moles of solute / kg of solvent ppm = mg solute / liter of solution ppb = microgram of solute / liter of solution %-by-mass = (grams of solute / grams of solution) x 100% To convert from %-by-mass to Molarity, assume 100g of solution,...

Chemistry 2A Lab 13: Solution Calculations Introduction This lab involves sample calculations using various concentration units. This lab will work with the following types of concentration units: % mass, % volume, % mass/volume, and molarity. A solution is the sum total of the solute and solvent. % mass= mass solute mass solution -100 volumesolute .100 % volume- volume solution % mass/volume mass solute volumesolution -100 Molarity moles solute liters solution The dilution of a liquid requires the addition of more...
