50 g of copper sulfate pentahydrate was completely dissolved in 100 ml of water. Determine the concentration of the resulting solution.

m (copper sulfate pentahydrate) = 50 g.
m (water) = 100 g.
Determine the concentration of the resulting solution. We write down the solution.
For this we use the following formula.
W = m r.v / m r-ra * 100%.
Where m r.v is the mass of the solute.
m solution is the mass of the solution.
First, determine the mass of the solution.
m solution = m r.v + m H2O.
m solution = 50 g + 100 g = 150 g.
Next, we determine the concentration of the resulting solution.
W = 50/150 * 100 = 33.3%.
This means that the concentration of the resulting solution is 33.3 percent.
Answer: the concentration of the resulting solution is 33.3 percent.
