The principal component of many kidney stones is calcium oxalate,CaC2O4. A kidney stone recovered from a typical patient contains 8.50×10^20 formula units of calcium oxalate.
How many moles of CaC2O4 are present in this kidney stone?
1 mole = 6.02x1023
so, how many moles in the kidney stone?
= 1.41x10-3 = 0.00141
