In 150 g of water, 25 g of sodium chloride was dissolved. determine the mass fraction of salt in the resulting solution.

To solve the problem, we perform the following actions:
First, we calculate the mass of the solution, for this we add the mass of salt to the mass of water, the result is the following
150 + 25 = 175
Further, in order for the mass fraction of salt in the solution, it is necessary to divide the mass of the salt by the mass of the solution and multiply by 100 percent, the result is the following
W = 25g / 175g × 100% = 14.3%
Therefore, the mass fraction of salt in the resulting solution is 14.3 percent.
Answer: the mass fraction of salt in the resulting solution is 14.3%.
