Question

A scientist makes and acid solution by adding drops of acid to 1.2 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, 40 drops were added to the water about what percentage of the solution is the acid.

Answer 1

Answer: 0.166% of the solution is acid

Explanation:

The scientist added 40 drops of acid to the water. Each drop has a volume of 0.05 mL. To find the total volume of the acid added, we can multiply the number of drops by the volume of each drop: 40 drops * 0.05 mL/drop = 2 mL.

Now, let's calculate the percentage of the solution that is acid. The total volume of the solution is 1.202 L, and the volume of the acid added is 2 mL.

To convert the volume of the acid to liters, we divide by 1000: 2 mL / 1000 = 0.002 L.

Now, we can calculate the percentage of the solution that is acid: (0.002 L / 1.202 L) * 100 = 0.166%.

Therefore, about 0.166% of the solution is acid.
