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%.
