To prepare 150 g of a solution with a mass fraction of sugar of 15%, it is necessary to find the mass of the substance.

m (sugar) = W (sugar) • m (solution) / 100% = 15% • 150 g / 100% = 22.5 g.

The mass of water will be equal to:

m (H2O) = m (solution) – m (sugar) = 150 – 22.5 = 127.5 g.

So you need to take 22.5 g of sugar and dissolve it in 127.5 g of water.
