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?

  • chemistry -

    1 mole = 6.02x1023

    so, how many moles in the kidney stone?

    8.5x1020/6.02x1023
    = 1.41x10-3 = 0.00141
