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

The target heart rate of the 45 year old client with a resting heart rate of 75 bpm is; 135 bpm
Complete question is;
A client is 45 years old and has a resting heart rate of 75 bpm using the karvonen formula what is their target heart rate at an exercise intensity of 60%.
We are given;
Age of client = 45 years
Resting Heart rate = 75 bpm
%Intensity = 60%
The karvonen formula is;
Target Heart Rate = [(max HR − resting HR) × %Intensity] + resting HR
Formula for maximum heart rate is;
Max HR = 220 - age
Max heart rate = 220 - 45
Max HR = 175 bpm
Thus;
Target Heart rate = [(175 - 75) × 0.6] + 75
Target Heart rate = (100 × 0.6) + 75
Target Heart rate = 60 + 75
Target Heart rate = 135 bpm
