20 g of sodium chloride was dissolved in 150 g of water. Determine the mass fraction of sodium chloride in the solution.
The mass of sodium chloride is 20 g.
The mass of water is 150 g.
Determine the mass fraction of sodium chloride in the solution.
To do this, do the following: divide the mass of sodium chloride by the mass of the solution.
W = m r.v. / m r-ra * 100%.
First, determine the mass of the solution. To do this, add the mass of water and soluble substance.
m solution = 20 + 150 = 170 g.
The mass of the solution is 170 grams.
Next, determine the mass fraction of the substance in the solution.
W = 20/170 * 100% = 11.8%.
Consequently, the mass fraction of sodium chloride in the solution is 11.8%.
Answer: W = 11.8%.
