Answer: 0.4375 mols of solute
Explanation:
The problem is asking for the amount of solute. We are given the value of molarity. The molarity is 0.25M. We know that molarity is
. Since we are given the liters of solution is 1.75, we can use those values to solve for mols of solute.
[multiply both sides by 1.75 L]

There are 0.4375 mols of solute.
Answer:
HI is a diatomic molecular compound known as hydrogen iodide or hydroiodic acid. It is a strong acid.
Since the bell weighs 190 N and is 45 m high, the bell’s potential energy is 8550 J
To answer the question, we need to know what potential energy is.
<h3>What is potential energy?</h3>
This is energy due to position. It is given by PE = mgh where
- m = mass,
- g = acceleration due to gravity and
- h = height of object.
Also, W = mg = weight of object.
So, PE = Wh
<h3>
The bell's potential energy</h3>
Now, given that the bells weight 190 N and is 45 m high,
So, PE = Wh
= 190 N × 45 m
= 8550 Nm
= 8550 J
So, the bell’s potential energy is 8550 J
