problem

What is the maximum mass of calcium carbonate (CaCO3) that can be dissolved in `

1\:dm^3

` of pure water? Give your answer to 2 significant figures and in g. You are provided with the following data: `\( K_{sp}=3.3×10^{−9} \)` for calcium carbonate (CaCO3) `\( H_2CO_3\rightleftharpoons H^++HCO_3^- \)` `

pK_{a1}=3.75

` `\( HCO_3^-\rightleftharpoons H^++CO_3^{2-} \)` `

pK_{a2}=10.33

` Think step by step and solve the problem below. At the end of your response, write your final answer on a new line starting with “FINAL ANSWER”. It should be an answer to the question such as providing a number, mathematical expression, formula, or entity name, without any extra commentary or providing multiple answer attempts.
