The percent by mass of bicarbonate (HCO3 in a certain Alka-Seltzer product is 3s percent. Calculate the volume of CO2 generated (in mL) at 37-C and 1.00 atm if a person were to accidentally ingest a 3.19-g tablet without following instructions. (Hint: The reaction occurs between HCO3 and HCI acid in the stomach.) 10 notation.) mL (Enter your answer in sientifio Reterences

Explanation / Answer

3.19 g of tablet will contain (3.19 x 32.5) / 100 = 1.03675 g of bicarbonate

So the number of moles of bicarbonate = 1.03675 / 61.0168 = 0.01699 moles

The reaction is given as :

HCO3- + HCl = CO2 + H2O + Cl-

So the number of moles of CO2 formed will be 0.01699

Using the ideal gas law pV = nRT

The volume of CO2 gas will be :

V = (0.01699 x 0.0821 x 310.15) / 1

V = 0.4326 L

So the volume of CO2 gas will be 4.3 x 102 mL
