When the solute in a solution is a solid, a convenient way to express the concentration is a mass percent (mass/mass), which is the grams of solute per 100g of solution. Percent by mass = mass of solute mass of solution × 100%. Suppose that a solution was prepared by dissolving 25.0g of sugar into 125g of water.

Web1. By using proportional sets or through simple multiplication, we find that: p = 0.27. r = 375. a = 0.0027. And as the question asks us for mg/g: 0.0027g = 2.7mg. Answer – the diluted product has a percentage strength of 0.27% w/w, a ratio strength of 1 in 375 w/w and an amount strength of 2.7 mg/g.
