TUMS is a popular remedy for acid indigestion. A typical TUMS tablet contains calcium carbonate plus  some inert substances. When ingested, it reacts with  the gastric juice (hydrochloric acid) in the stomach  to give off carbon dioxide gas. When a 1.328-g tablet  reacted with 40.00 mL of hydrochloric acid (density =  1.140 g/mL), carbon dioxide gas was given off and the  resulting solution weighed 46.699 g. Calculate the  number of liters of carbon dioxide gas released if its  density is 1.81 g/L.

Basic Chemical Calculations (Process and Variables)

A basic chemical calculation involves the application of the law of chemical proportions to various reactions and material and energy balance calculations on various chemical processes. Basic chemical calculation helps students analyze various chemical processes and develop problem-solving skills. The chemical manufacturing processes are divided into unit operations involving physical changes of material and unit processes involving the chemical transformation of materials. For instance, fluid flow, heat transfer, and mass transfer are unit operations, and oxidation, reduction, and pyrolysis are unit processes.
