1. How many ounces are in one gallon?

• A. 64 ounces
• B. 128 ounces
• C. 100 ounces
• D. 150 ounces

Correct answer: B

Rationale: The correct answer is B: 128 ounces. One gallon is equivalent to 128 ounces. This conversion relationship is commonly used in cooking, baking, and various liquid measurements. Choice A (64 ounces) is incorrect as it represents half the amount of a gallon. Choice C (100 ounces) and Choice D (150 ounces) are also incorrect, as they do not accurately reflect the conversion of a gallon to ounces.

2. Is 0.25 mg equal to 250 mcg?

• A. TRUE
• B. FALSE
• C. Sometimes
• D. None of the above

Correct answer: A

Rationale: The correct answer is A: TRUE. 0.25 mg is indeed equal to 250 mcg. This conversion is obtained by multiplying 0.25 mg by 1000 to convert it to micrograms. In pharmaceuticals, it is crucial to understand and convert between different dosage units accurately. Choice B is incorrect as the two quantities are equivalent. Choice C, 'Sometimes,' is misleading as the conversion from milligrams to micrograms follows a consistent ratio. Choice D, 'None of the above,' is incorrect as there is a definitive equivalence between the provided quantities.

3. What is 0.45 liters in milliliters?

• A. 450 ml
• B. 45 ml
• C. 4.5 ml
• D. 0.45 ml

Correct answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter equals 1000 milliliters. Therefore, 0.45 liters is equivalent to 450 milliliters. Choice B, 45 ml, is incorrect as it represents the conversion of 0.045 liters to milliliters. Choice C, 4.5 ml, is incorrect as it represents the conversion of 0.0045 liters to milliliters. Choice D, 0.45 ml, is incorrect as it is the initial quantity in milliliters and not the result of the conversion.

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 0.6 liters to milliliters.

• A. 60 ml
• B. 600 ml
• C. 6 ml
• D. 6000 ml

Correct answer: B

Rationale: To convert 0.6 liters to milliliters, you need to multiply by 1000 since 1 liter equals 1000 milliliters. 0.6 * 1000 = 600 ml, which is the correct answer. Choice A (60 ml) is incorrect because it represents 0.06 liters. Choice C (6 ml) is incorrect as it would be the milliliter equivalent for 0.006 liters. Choice D (6000 ml) is incorrect as it would be the milliliter equivalent for 6 liters.
