Concept explainers
Interpretation: The following problem can be solved by the concept of molar mass.
Concept introduction: The molar mass is defined as the mass of a chemical substance (element or compound) divided by amount of the substance. It is expressed in kg/mol (SI units). The molar mass of a chemical compound is the sum of standard
Given: In this question, it is given that one Tums tablet has 500 mg of calcium carbonate which helps to neutralizethe stomach acid. We need to find out the (a) formula of calcium carbonate (b) molar mass of calcium carbonate, (c) number of moles of calcium carbonate present in one roll (12 tablets) of Tums, and (d) amount of calcium in two Tums tablets, (e) the Tums tablets needed daily to supply the requisite calcium when the recommended amount of Ca2+ in older women is 1500 mg.
