Answer: The correct answer is A. 11.5 atm. The temperature is held constant at 293 K, therefore, we can use Boyle's Law to determine the initial pressure. Boyle's Law states that there is an inverse relationship between pressure and volume of gases. Therefore, as volume increases, the pressure will decrease and vice versa.
Further Explanation:
Boyle's Law can be mathematically expressed as:
In this problem, we are given the values:
P(initial) = ?
V(initial) = 80 L
P (final) = 0.46 atm
V (final) = 2000 L
Plugging in these values into the equation:
The initial pressure was 11.5 atm. Since the volume increased or expanded, the space where the gas particles move is bigger, so the frequency of collisions with the wall of the container and with other particles are effectively decreased. This, therefore, decreases the pressure from 11.5 to 0.46 atm.

The pH of the diluted HCl solution is 1.3.
Explanation:
Given:
The concentrated HCl solution of 8.0 M. The 1.5 mL of 8.0 M HCl is diluted with water to 250 mL volume.
To find:
The pH of the diluted HCl solution.
Solution
- The concentration of the HCl solution before dilution =
- The volume of the HCl solution taken for dilution =
- The concentration of the HCl solution after dilution =
- The volume of the HCl solution after dilution =
Using the Dilution equation:
The concentration of diluted HCl solution = 0.048 M
In the 1 M solution of HCl, there are 1 M of hydrogen ion, then the concentration of hydrogen ions in 0.048 M of HCl will be:
The pH of the diluted HCl solution :
The pH of the diluted HCl solution is 1.3.
