Question

How many grams of oil are in a 500 g solution that is 5%w/w oil?

Mass % of any component of the solution = (Mass of the component in the solution / Total mass of the solution) x 100

Therefore,

mass of oil = mass % × mass of solution / 100% = 5% × 500g / 100% = 25 g

Answer: there are 25 grams of oil in the solution.
