How much citric acid is in 0.5 mL of water?

A
0.00015 g

B
0.00015 mL

C
0.00020 g

D
0.00020 mL

The question asks about the citric acid content in the water, not the amount of water itself. Therefore, the answer choices provided do not make sense.

To determine the amount of citric acid in the water, we would need to know the concentration of citric acid in the water. Depending on the concentration, we could calculate the amount of citric acid in 0.5 mL of water.

Without the concentration of citric acid provided, it is not possible to accurately determine the amount of citric acid in 0.5 mL of water.
