1. What is the conversion factor from milliliters to liters?

• A. 0.001 liters
• B. 0.01 liters
• C. 1 liter
• D. 10 liters

Correct answer: A

Rationale: To convert milliliters to liters, you need to divide by 1000 since there are 1000 milliliters in a liter. Therefore, the correct conversion factor is 0.001 liters (1 liter = 1000 milliliters). Choice B (0.01 liters) is incorrect as it suggests dividing by 100, which is not the correct conversion. Choice C (1 liter) is incorrect because it is the equivalent value in liters, not the conversion factor. Choice D (10 liters) is incorrect as it is not the correct conversion of milliliters to liters.

2. What is 0.1 mg to mcg?

• A. 100 mcg
• B. 10 mcg
• C. 1000 mcg
• D. 1 mcg

Correct answer: A

Rationale: To convert milligrams to micrograms, you need to multiply by 1000. Therefore, 0.1 mg is equal to 100 mcg. This conversion is commonly used in medical calculations. Choice B (10 mcg) is incorrect because it would be the conversion from milligrams to micrograms if multiplied by 100, not 10. Choice C (1000 mcg) is incorrect as it would be the conversion from grams to micrograms if multiplied by 1000. Choice D (1 mcg) is incorrect as it represents the original unit without conversion.

3. What is the value of one femtometer (fm) in meters?

• A. 10^-15 meters
• B. 10^-9 meters
• C. 10^-12 meters
• D. 10^-18 meters

Correct answer: A

Rationale: A femtometer is equivalent to 10^-15 meters. The prefix 'femto-' signifies a factor of one quadrillionth (10^-15), making choice A the correct answer. Choice B (10^-9 meters) represents a nanometer, not a femtometer. Choice C (10^-12 meters) corresponds to a picometer, not a femtometer. Choice D (10^-18 meters) is even smaller than a femtometer and refers to an attometer, not a femtometer.

4. How many milliliters are in 2 liters?

• A. 20 mL
• B. 200 mL
• C. 2,000 mL
• D. 20,000 mL

Correct answer: C

Rationale: To convert liters to milliliters, you need to multiply the number of liters by 1,000 since there are 1,000 milliliters in 1 liter. Therefore, 2 liters x 1,000 = 2,000 milliliters. Choices A, B, and D are incorrect because they do not account for the correct conversion factor from liters to milliliters.

5. How many centimeters are in one millimeter?

• A. 1/100 cm
• B. 0.1 cm
• C. 1 cm
• D. 10 cm

Correct answer: B

Rationale: The correct answer is B: 0.1 cm. One millimeter is equal to 0.1 centimeters, not 1/100th cm as mentioned in choice A. Choice C, 1 cm, is incorrect as a millimeter is smaller than a centimeter. Choice D, 10 cm, is incorrect as it incorrectly magnifies the conversion, making a millimeter larger than a centimeter. Therefore, the accurate conversion is that one millimeter equals 0.1 centimeters.
