The final volume of the diluted acid that was initially in a 55 mL bottle of 12 M HCl and diluted with water to a 2.5 M HCl solution is 264mL.
<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
12 × 55 = 2.5 × V2
660 = 2.5V2
V2 = 264mL
Therefore, the final volume of the diluted acid that was initially in a 55 mL bottle of 12 M HCl and diluted with water to a 2.5 M HCl solution is 264mL.

Answer:I would have to say d because isn’t that what they make phones out of and it has to be safe right ?
Explanation:
3.9 grams CaCO3
The mass of 2.0 L of water with a density of 1.00 g/ml is 2000 grams.And 1 ppm of that is 2000 / 1000000 = 0.002 grams. So just multiply by the ppm of CaCO3, giving 0.002 g * 1.95x10^3 = 3.90 grams.
Since the least accurate datum we have is 2 significant figures, the result should be rounded to 2 significant figures, giving 3.9 grams.
The step in the water cycle when this happens is Condensation
