Answer: 1.14
Explanation:

To find the molarity of the acid, we will utilize the equation derived from the neutralization process:

where
are the n-factor, molarity, and volume for the acid and
represent the n-factor, molarity, and volume for NaOH.
We know that:

By substituting the known values into the equation, we get:

To determine the pH of gastric juice:
The molarity amounts to = 0.072

Thus, the pH level of the gastric juice is 1.14
Answer: The correct option is (1).
Explanation:
Group 16 is the third-from-last column in the periodic table and is known as the oxygen family.
Members of this group include oxygen, sulfur, selenium, tellurium, and polonium.
Elements in Group 16 have 6 valence electrons in their outermost shell.
The electronic configuration of sulfur is
.
Because sulfur belongs to Group 16, it has 6 valence electrons.
