Solved: Calcium oxalate (CaC2O4), the main component of
Chapter 4, Problem 102P(choose chapter or problem)
Calcium oxalate \(\left(\mathrm{CaC}_{2} \mathrm{O}_{4}\right)\), the main component of kidney stones, is insoluble in water. For this reason it can be used to determine the amount of \(\mathrm{Ca}^{2+}\) ions in fluids such as blood. The calcium oxalate isolated from blood is dissolved in acid and titrated against a standardized \(\mathrm{KMnO}_{4}\) solution, as shown in Problem 4.99. In one test it is found that the calcium oxalate isolated from a 10.0-mL sample of blood requires 24.2 mL of \(9.56 \times 10^{-4}\) M \(\mathrm{KMnO}_{4}\) for titration. Calculate the number of milligrams of calcium per milliliter of blood.

ANSWER:
Step 1 of 3
The goal of the problem is to calculate the number of milligrams of calcium per milliliter of blood.
Given:
Volume of blood = 10.0 mL
Volume of 
Molarity of
The balanced equation is:
