Question

A scientist makes an acid solution by adding drops of acid to 12 L of water. The final volume of the acid solution is 1,202 L. Assuming the volume of each drop is 0.05 ml, how many drops were added to the water? About what percent of the acid solution is acid. Find the number of drops of acid that were added to the solution.

Answer 1

The number of drops of acid added to the solution is 23,800,000. The percentage of the acid solution that is acid is 99.00%.

Step-by-step explanation:

To find the number of drops of acid that were added to the solution, we can calculate the change in volume. The initial volume of water is 12 L and the final volume of the acid solution is 1202 L. This means that the acid solution was added in a volume of 1202 - 12 = 1190 L.

The volume of each drop is 0.05 mL, so to find the number of drops, we divide the volume of the acid solution by the volume of each drop: 1190 L / 0.05 mL = 23,800,000 drops.

To calculate the percentage of the acid solution that is acid, we can use the formula:

Percentage = (Volume of acid / Total volume) * 100%

In this case, the volume of acid is 1190 L and the total volume is 1202 L. Plugging these values into the formula we get:

Percentage = (1190 L / 1202 L) * 100% = 99.00%
