Interpretation:
Is a 10% sodium hydroxide solution made by dissolving 10 grams of the solid in 100 mL of water, and if you should insisting to dissolve the 10 g of solid hydroxide in only 90 g of water is to be explained.
Concept Introduction:
% w/w (weight per weight) is used where the weight of each chemical is used and not the volume (example, If dissolve 10 g of fat in 90 g ethanol so the total mass of the whole solution is 100 g, then I have made a 10% w/w solution of fat).
% w/v (weight per volume) is used where a solid chemical is dissolved in liquid (example, if I dissolve 10 g of table salt, sodium chloride, to make up a total volume of 100 mL of solution then I have made a 10% w/v solution of sodium chloride)
