Answer:
Mass percent concentration: 25,2% m/m
Explanation:
The percentage mass by mass indicates the grams of solute in 100 grams of solution. We convert the ml of water into g from the density formula:
δ= m/v m=δx v= 1 g/ml x 115 ml= 115 g
115g solution-----29 g NaCl
100g solution----x=(100g solutionx29 g NaCl)/115g solution
x=25,2173913 g NaCl
The answer is 71.5g of potassium sulfate
It is easiest to tell if a solution is saturated if there is residue on the bottom. If it crystallized, the solution is saturated. If it is a supersaturated solution, there will not be crystallization unless more of the solute is added, at which point all of it will crystallize.
