The pH of the solution of aniline is; pH = 4.64
<h3>pH of aniline solution</h3>
According to the question;
- We are required to determine the hydrogen ion concentration, pH of the given aniline solution.
Since, the given Kb is kb = 4. 3 × 10⁻¹⁰.
Hence, it follows that;
On this note, the pH of aniline solution is;
pH = 4.64.
Ultimately, the pH of the aniline solution given is; 4.64

John will need to sleep for 10.3 hours before his second exam so that the
average of his two exam scores is an 80.
We were given
8 hours of sleep = 70
To get average of 80
<u>70+ x</u> = 80
2
Cross multiply:
70+x = 160
x= 160-70
= 90.
If 8 hours of sleep = 70
x hours of sleep = 90
Cross multiply
8× 90 = 70 × x
720 = 70x
x = 720/70
x = 10.2857
≈ 10.3 hours of sleep
