Will 260.0 milligrams of calcium carbonate raise the pH of 75.0 milliliters of stomach fluid from a low pH of 1.00 into the normal pH range of 1.50-3.50? In the last discussion, you calculated that 260.0mg of calcium carbonate is 0.2600g of calcium carbonate. The next step is to figure out the formula of calcium carbonate and to calculate the molar mass of calcium carbonate in grams per mole. Submit a reply that that tells how you decided to approach the problem and shows the work that results in an answer. Use correct units and significant figures and correct symbols for elements and math. In addition, select another student's explanation that makes sense to you and reply with a comment about the insight you gained from their answer. Calcium carbonate is an ionic compound. Ionic nomenclature is in section 2.8. Molar mass is described on page 74 in section 2.8 of the textbook.
