1. What is 0.5 liters to milliliters?

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

Correct answer: A

Rationale: The question asks for the conversion of 0.5 liters to milliliters. The correct answer is 500 ml, which is derived from the standard conversion factor where 1 liter is equal to 1000 milliliters. Choice B, 50 ml, is incorrect as it represents the conversion of 0.05 liters to milliliters. Choice C, 5 ml, is incorrect as it corresponds to the conversion of 0.005 liters to milliliters. Choice D, 0.5 ml, is incorrect as it is the same value given in the question but in milliliters.

2. Which of the following is equal to 0.13 inches?

• A. 0.013 inches
• B. 1.3 inches
• C. 0.13 inches
• D. 13 inches

Correct answer: C

Rationale: The correct answer is C: 0.13 inches. When converting decimals to inches, the value remains the same. Choice A, 0.013 inches, represents a smaller value than 0.13 inches as it has an extra zero. Choice B, 1.3 inches, is incorrect as it is a larger value than 0.13 inches. Choice D, 13 inches, is significantly larger than 0.13 inches, making it an incorrect conversion.

3. What is 0.5 liters equivalent to?

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

Correct answer: A

Rationale: 0.5 liters is equivalent to 500 milliliters. This conversion is straightforward because 1 liter equals 1000 milliliters. Choice A is correct because it accurately converts 0.5 liters into milliliters. Choices B, C, and D are incorrect as they do not correctly convert the given volume into milliliters.

4. What unit is used to measure density in the metric system?

• A. grams per cubic meter (g/m³)
• B. grams per liter (g/L)
• C. grams per cubic centimeter (g/cm³)
• D. grams per square meter (g/m²)

Correct answer: A

Rationale: Density is measured in grams per cubic meter (g/m³) in the metric system. This unit represents the amount of mass (in grams) per unit volume (cubic meter). Choice B, grams per liter (g/L), is incorrect as density is not typically measured in liters. Choice C, grams per cubic centimeter (g/cm³), is a common unit for density but not the standard SI unit. Choice D, grams per square meter (g/m²), is a unit for surface density, not volumetric density. Therefore, the correct unit for measuring density in the metric system is grams per cubic meter (g/m³).

5. Convert 3,540 liters to milliliters (mL).

• A. 354,000 mL
• B. 3,540,000 mL
• C. 35,400 mL
• D. 35,400,000 mL

Correct answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1,000 because there are 1,000 milliliters in 1 liter. Therefore, 3,540 liters × 1,000 = 3,540,000 milliliters. Choices A, C, and D are incorrect because they do not correctly convert liters to milliliters. A, C, and D are off by a factor of 1,000, as they do not account for the conversion factor between liters and milliliters.
