Stoichiometry in Aqueous Solutions Part 1
Calculate the concentration (in mol/L) of chloride ions in each solution.
a) 19.8g of potassium chloride dissolved in 100 mL of solution.
b) 26.5g of calcium chloride dissolved in 150.0 mL of solution.
Stoichiometry in Aqueous Solutions Part 2
The leaves of a rhubarb plant contain a high concentration of oxolate ions, C2
. To determine the percent of oxolate ions, a student measured the mass of some leaves. The student grounds up the leaves and added excess calcium chloride solution to precipitate calcium oxalate. The student tested 238.6g of leaves. The dried mass of calcium oxolate was 0.566g. What was the mass percent of oxolate ions in the leaves?
