Question

Calculate the mass of 0. 5 moles of caco3 in grams with procedure

Answer 1

Explanation:

As demonstrated by Frank T. Edelmann the solubility of Ca in ambient water is 14 mg/L and based on the simplified explanation by Eron R Raines you may need 1.25 g of CaCO3 to reach the 1 g/L concentration of Ca. In this situation, you should be aware of the fact that you may not have a 1 g/L Ca solution by adding 1.25 g of pure carbonate calcium to the water, unless you could dissolve all the CaCO3 by the means of acidified compositions (like injecting CO2 gas into the water). Otherwise, you will have a 14 mg/L Ca solution, even after adding 1.25 g of pure calcium carbonate to 500 mL of water.
