1. Convert 0.075 mg to micrograms.

• A. 75 mcg
• B. 7.5 mcg
• C. 0.75 mcg
• D. 750 mcg

Correct answer: D

Rationale: To convert milligrams to micrograms, you need to multiply by 1000, not 10000. Therefore, to convert 0.075 mg to mcg, you multiply 0.075 by 1000, giving you 75 mcg. The correct answer is not provided in the choices, and the correct conversion is 75 mcg, which is not listed as an option. Choices A, B, and C are incorrect because they do not reflect the correct conversion factor. Choice D, 750 mcg, is a common mistake made by incorrectly adding a zero. It is important to remember that the conversion from milligrams to micrograms involves multiplying by 1000, not adding extra zeros.

2. What is the equivalent of 500 milliliters in liters?

• A. 0.05 liters
• B. 0.5 liters
• C. 5 liters
• D. 50 liters

Correct answer: B

Rationale: To convert milliliters to liters, you need to divide by 1000 since 1 liter is equal to 1000 milliliters. Therefore, 500 milliliters divided by 1000 equals 0.5 liters. Choice A (0.05 liters) is incorrect because it represents 50 milliliters, not 500 milliliters. Choice C (5 liters) and Choice D (50 liters) are both incorrect as they are higher values and do not accurately represent the conversion of 500 milliliters to liters.

3. How many grams are in one kilogram?

• A. 100 grams
• B. 1000 grams
• C. 500 grams
• D. 2000 grams

Correct answer: B

Rationale: The correct answer is B: 1000 grams. This is because by definition, 1 kilogram is equal to 1000 grams. Choice A, 100 grams, is incorrect as it underestimates the actual conversion. Choice C, 500 grams, and Choice D, 2000 grams, are also incorrect as they do not align with the correct conversion factor of 1 kilogram to 1000 grams.

4. What is the official name of the metric system?

• A. International Measurement System
• B. International System of Units
• C. Metric Unit System
• D. Measurement System of Units

Correct answer: B

Rationale: The official name of the metric system is the International System of Units (SI). The International System of Units is a globally recognized standard for measurement. Choice A, 'International Measurement System,' is incorrect as it does not accurately reflect the official name. Choice C, 'Metric Unit System,' while related to the metric system, is not the precise official name. Choice D, 'Measurement System of Units,' is a mix-up of terms and does not represent the correct official name of the metric system.

5. Convert 0.025 mg to micrograms.

• A. 25 mcg
• B. 250 mcg
• C. 2.5 mcg
• D. 0.25 mcg

Correct answer: A

Rationale: To convert milligrams to micrograms, you multiply by 1000, not 10000. Therefore, 0.025 mg equals 25 mcg. Choice B (250 mcg) is incorrect as it incorrectly multiplies by 10000. Choice C (2.5 mcg) is incorrect as it incorrectly divides by 10. Choice D (0.25 mcg) is incorrect as it incorrectly multiplies by 10.
