In 5 liters of water, 500 grams of copper sulfate was dissolved. Calculate the mass fraction of copper sulfate (2) in the resulting solution.
The volume of water is 5 liters.
The mass of copper sulfate is 500 g.
Determine the mass fraction of copper sulfate in the resulting solution.
First, you need to determine the mass of water. For this we use the following formula.
m = pV.
V = 5 l = 5000 ml.
m = 5000 ml * 1 g / ml = 5000 g.
Next, we determine the mass of the solution.
m solution = 5000 + 500 = 5500 g.
Next, we determine the mass fraction of salt in the resulting solution.
W = m r.v / m r-ra * 100%.
W = 500/5500 * 100 = 9.09%.
Therefore, the mass fraction of copper sulfate in the solution is 9.09 percent.
Answer: W = 9.09%.
