Answer:
⇒ n = 2.4088 × 10²⁴
- So, the no of atoms in 4 moles of helium is 2.4088 × 10²⁴.
Explanation:
In a solution, when the concentrations of a weak acid and its conjugate base are equal, the -log of the concentration of H+ and the -log of the Ka are equal.
<h3>
What is Henderson-Hasselbalch equation ?</h3>
- This formula is frequently used to determine the pH of buffer solutions. A weak acid and its conjugate base make up buffer solutions.
- To find the pH of the buffer solution, we obtain the pKa of the weak acid and add it to the log of the concentration of the conjugate base divided by the concentration of weak acid.
- So whenever the concentration of the weak acid is equal to the concentration of the conjugate base, the pH of the buffer solution is equal to the pKa of the weak acid.
