Metric Conversions for TEAS 7

Correct Answer: A

Rationale: To convert liters to milliliters, you multiply by 1000 since 1 liter = 1000 ml. Therefore, 0.5 liters x 1000 = 500 ml. Thus, the correct answer is A (500 ml). Choice B (50 ml) is incorrect as it is 10 times smaller than the correct answer. Choice C (5 ml) is incorrect as it is 100 times smaller than the correct answer. Choice D (0.5 ml) is incorrect as it is the same value in milliliters, not the conversion of liters to milliliters.
