Stalactites-The Long, Icicle-Like Formations That Hang from the Ceilings of Caves-Are

Stalactites-the long, icicle-like formations that hang from the ceilings of caves-are formed from recrystallizing minerals like calcite (calcium carbonate, CaCO₃, 100.09/mol) .The K_sp of calcium carbonate is 4.5 * 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?

B) 4.5 * 10⁴ L
C) 1.5 * 10⁵ L
D) 1.4* 10⁶ L
E) 4.5 * 10⁹ L
