Stalactites--the long icicle, icicle like formations that hang from the ceilings of caves--are formed from recrystallizing minerals like calcite (calcium carbonate, CaCO3, 100.09 g/mol). The Ksp of calcium carbonate is 4.5 x 10^-9. What is the minimum volume of dripping water saturated with calcium carbonate that would be required to form a small stalactite that had a mass of 1.000 kg?

Answer choices:

a. 1.5 x 10^4 L

b. 1.5 x 10^5 L

c. 4.5 x 10^4 L

d. 1.4 x 10^6 L
