| The mass of water is 150 g.

The sugar mass is equal to – 5 g.

Determine the mass fraction of sugar in the resulting solution. We write down the solution.

In order to solve this problem, you must use the following formula.

W = m pv / m solution * 100%.

First, you need to determine the mass of the solution.

m solution = m r.v + m H2O.

m solution = 150 + 5 = 155 g.

Therefore, the mass of the solution is 155 grams.

Next, we determine the mass fraction of sugar in the solution.

W = 5/155 * 100 = 3.22%.

Therefore, the mass fraction of sugar is 3.22 percent.

Answer: W = 3.22%.
