Assuming that the calcium is purely from the marble sample, and basing your calculations off of the molar solubility, calculate how many grams of calcium are present in this water sample. Note that the cone has a base radius of 10.00mm and a height of 480.8mm. molar solubility of CaCO3 = M amount of calcium= --× 103 g
