Question
What is the percentage strength (w/w) of a solution made by dissolving $250 \mathrm{~g}$ of potassium chloride in $750 \mathrm{~mL}$ of water?
Step 1
Given that the mass of potassium chloride is 250 g and the volume of water is 750 mL, we need to convert the volume of water to mass using the density of water, which is 1 g/mL. Mass of water = volume of water x density of water Mass of water = 750 mL x 1 g/mL = Show more…
