Solution Concentration Solution Concentration Read 281 – 283. Try questions 1 – 8 (show work) Concentration = quantity of solute quantity of solution (not solvent) There are 3 basic ways to express concentration: 1) percentages, 2) very low concentrations, and 3) molar concentrations 1) % concentration can be in V/V, W/W, or W/V Like most %s, V/V and W/W need to have the same units on top and bottom. W/V is sort of in the same units; V is mostly water and water’s density is 1 g/mL or 1 kg/L 3 g H 2 O 2 /100 mL solution 3 g H 2 O 2 /100 g

Solution Concentration Solution Concentration 2) Expressing concentrations in parts per million (ppm) requires the unit on top to be 1,000,000 times smaller than the unit on the bottom E.g. 1 mg/kg or μ g/g Multiples of 1000 are expressed in this order μ _, m_, _, k_ (“_” is the base unit) (pg.631) Notice that any units expressed as a volume must be referring to a water solution (1L = 1kg) For parts per billion (ppb), the top unit would
