Question
The volume of an adult's stomach ranges from 50.0mL when empty to 1.00L when full.
a. If the volume of a stomach is 565 mL and its contents have a pH of 2.10, what is the molarity of the [H*] that the
stomach contains?
b. Assuming that all the H* comes from HCI, how many grams of sodium bicarbonate, NaHCO3 is necessary to
totally neutralize the stomach acid? The reaction that occurs in the stomach is shown below:
HCI + NaHCO3
CO2 + H₂O + NaCl
