Answer:
Solving for the Percent by Volume
The v/v concentration of acetic acid in the stop bath is 24.6%.
Explanation:
To answer the question, we need to identify certain information stated in the question. Let us write down what’s given:
Volume of solute = 160 mL
Volume of solution = 650 mL
Next, we need to determine what is required, in this case, the percent by volume. Now, let us look at the formula:
v/v concentration = (solute volume / volume of the solution) * 100
Solution:
Percent by Volume = (160 / 650) * 100
Percent by Volume = 0.2461538461538462 * 100
Percent by Volume = 24.61538461538462
Rounded off = 24.6%
Therefore, the final answer is 24.6%
Explanation:
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

Answer:
The quarter rest indicates that you remain silent (take a rest from playing) for one beat. You can count these measures as "one two three."
