Question 23 1 Point What is the pH of 0.00187 M HCl? (HCl is a strong acid) BLANK-1 (give your answer to 3 significant figures) BLANK-1
Gastric acid pH can range from 1 to 4, and most of the acid is HCl. For a sample of stomach acid that is 2.53 Times 10^-3 M in HCl, how many moles of HCl are in 12.7 mL of the stomach acid? Express the amount to three significant figures and include the appropriate units.
Calculate the pH and pOH of the following solutions: a. stomach acid in which [HCl] = 0.155 M b. 0.00500 M HNO3 c. a 2:1 mixture of 0.0125 M HCl and 0.0125 M NaOH d. a 3:1 mixture of 0.0125 M H2SO4 and 0.0125 M KOH
When the parietal cells of the stomach secrete HCl, the initial HCl concentration is about 160 mM. What is the pH at this concentration? (when considering significant figures with logarithms, the number of sig figs in the original argument is the number of digits after the decimal point in your answer)
Part B Gastric acid pH can range from 1 to 4, and most of the acid is HCl. For a sample of stomach acid that is 1.07x10-2 M in HCl, how many moles of HCl are in 13.5 mL of the stomach acid? Express the amount to three significant figures and include the appropriate units. View Available Hint(s) ? DI MÅR Value O 2 Units amount of HCI = amount of HCl = Submit

Calcium carbonate (CaCO3) reacts with stomach acid (HCl, hydrochloric acid) according to the following equation: CaCO3(s) + 2HCl(aq) + CO2(g) + H2O(l) + CaCl2(aq) A typical antacid contains CaCO3. If such an antacid is added to 25.0 mL of a solution that is 0.300 M in HCl, how many grams of CO2 gas are produced? Express the mass to three significant figures and include the appropriate units.
