1 BaCl molecule has three atoms hence 3 BaCl molecules have 9 atoms
The final volume of the diluted solution that initially has a volume 10.0 mL sample and concentration of 5.00M HCl is 232.6mL.
<h3>How to calculate volume?</h3>
The volume of a solution can be calculated using the following formula:
C1V1 = C2V2
Where;
- C1 = initial concentration
- C2 = final concentration
- V1 = initial volume
- V2 = final volume
10 × 5 = 0.215 × V2
50 = 0.215V2
V2 = 50/0.215
V2 = 232.6mL
Therefore, the final volume of the diluted solution that initially has a volume 10.0 mL sample and concentration of 5.00M HCl is 232.6mL.

Answer:
A beam balance is an example of a first class lever.
Explanation:
A beam balance is an example of a first class lever. In a first class lever, the fulcrum is between the effort (force) and the load. The effort (force) moves over a large distance to move the load a smaller distance.
Other examples of first class lever are pliers, scissors, a crow bar, a claw hammer, a see-saw and a weighing balance etc.
Impure substance, because pure would be dirt from the earth
That would be electromagnetic waves .
They are of very high energy.
