Question

Enter your answer in the provided box. TUMS is a popular remedy for acid indigestion. A typical TUMS tablet contains calcium carbonate stomach to give off carbon dioxide gas. When a 1.34l-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 i.Si g/L.

Answer 1

Ans:- Part1

Here the mass of the resulting solution when carbon dioxide was released is given as

mass = 46.699g

density = 1.81g/L

Therefore volume of carbon dioxide gas released

Volume = Mass / Density

             = 46.699/1.81

             = 25.8L

Ans: Part B

Given mass of copper Cu = 42.39 g

Molar mass of Copper = 63g

Avagadro's number = 6.023x10²³

Number of atoms = given mass x Avagadro's number /Molar mass

                          = 42.39 x 6.023x10²³ / 63

                         = 4.05 x 10²³ atoms.
