Question

If you have 80 g of solute and want to make a 56% w/w solution how many grams of water should you add, rounded to the nearest thousandth

Solution

Percentage of the solvent (water in given case) in the solution: 100% – 56% = 44%

Thus, we have the proportion:

80 g (solute) – 56%

X g (water) – 44%

Hence X = (80 g · 44%) / 56% = 62.857 g

Answer: 62.857 g
