(a) A small bubble rises from the bottom of a lake, where the temperature and
pressure are 8ºC and 6.4 atm, to the water's surface, where the temperature is
25ºC and pressure is 1.0 atm. Calculate the final volume (in ml) of the bubble if
its initial volume was 2.1 ml.
(b)The percent by mass of bicarbonate (HCO3-) in a certain Alka-Seltzer product is
32.5 %. Calculate the volume of CO2 generated at 37ºC and 1.00 atm when a
person ingests a 3.29g tablet. (Hint: The CO2 is produced by the reaction of
HCO3- and the H+ ions in the stomach)
It provides two applications of ideal gas law, such as finding the initial volume of a bubble and volume of CO2 produced from alka-seltzer product.
