1. How many milliliters are in 1 ounce?

• A. 20 ml
• B. 30 ml
• C. 40 ml
• D. 50 ml

Correct answer: B

Rationale: The correct answer is B: 30 ml. 1 ounce is equivalent to 30 milliliters. This conversion is a common one in many contexts involving liquid measurements. Choice A (20 ml), Choice C (40 ml), and Choice D (50 ml) are incorrect conversions and do not represent the accurate conversion between ounces and milliliters.

2. How many liters are in 3,000 milliliters?

• A. 0.3 liters
• B. 30 liters
• C. 3 liters
• D. 0.03 liters

Correct answer: C

Rationale: To convert milliliters to liters, you need to divide by 1,000 since there are 1,000 milliliters in a liter. Therefore, 3,000 milliliters / 1,000 = 3 liters. Choice A '0.3 liters' is incorrect as it represents 300 milliliters, not 3,000. Choice B '30 liters' is incorrect as it is the result of multiplying by 10 instead of dividing by 1,000. Choice D '0.03 liters' is incorrect as it represents 30 milliliters, not 3,000.

3. How many quarts are in 1 gallon?

• A. 2 quarts
• B. 4 quarts
• C. 3 quarts
• D. 1 quart

Correct answer: B

Rationale: The correct answer is B: 4 quarts. There are 4 quarts in 1 gallon. This conversion is based on the fact that 1 gallon is equivalent to 4 quarts. Choice A is incorrect as 2 quarts are half of a gallon, not a whole gallon. Choice C is incorrect as 3 quarts is less than a gallon. Choice D is incorrect as it represents only one quart, whereas the question asks for the quantity in a gallon.

4. What is 0.09 liters in milliliters when converted?

• A. 0.09 ml
• B. 90 ml
• C. 900 ml
• D. 9 ml

Correct answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1,000 since there are 1,000 milliliters in a liter. Therefore, 0.09 liters x 1,000 = 90 milliliters. Choice A, 0.09 ml, is incorrect as it represents the original volume in milliliters. Choices C and D, 900 ml and 9 ml, are incorrect as they miscalculate the conversion from liters to milliliters.

5. How many milliliters are in 0.5 liters?

• A. 500 ml
• B. 50 ml
• C. 5 ml
• D. 0.5 ml

Correct answer: A

Rationale: To convert from liters to milliliters, you need to multiply by 1000 since there are 1000 milliliters in a liter. Therefore, 0.5 liters x 1000 = 500 milliliters. This conversion is common in various contexts where different units of volume are used. Choices B, C, and D are incorrect as they do not reflect the correct conversion factor from liters to milliliters.
