WebSep 15, 2024 · 9.2: Concentration. Calculate percentage concentration (m/m, v/v, m/v), ppm and ppb. Calculate the molarity of a solution. Use concentration units to calculate the amount of solute in a solution. Use molarity to determine quantities in chemical reactions. Determine the resulting concentration of a diluted solution. Webgrams of solute = (wt% solution) x (ml of water) ÷ (100 – wt% solution) As an example, to make 100 ml of 10% NaCl (table salt) solution, use the previous formula to find out how much NaCl you need: grams of NaCl = (10) x (100) ÷ (100 – 10) = 11.1 g. Now you can make your solution: dissolve 11.1 g NaCl in 100 ml of water.
