1. What is 0.04 liters converted to milliliters?

• A. 40 ml
• B. 4 ml
• C. 400 ml
• D. 0.4 ml

Correct answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1,000 since there are 1,000 milliliters in a liter. So, to convert 0.04 liters to milliliters, you would multiply 0.04 by 1,000, giving you 40 milliliters. This means that choice A, '40 ml', is the correct answer. Choices B, C, and D are incorrect because they do not correctly convert liters to milliliters. Choice B, '4 ml', is incorrect as it is 10 times smaller than the correct conversion. Choice C, '400 ml', is incorrect as it is 10 times larger than the correct conversion. Choice D, '0.4 ml', is incorrect as it is one-tenth of the correct conversion.

2. What is the correct conversion of 35,400 milligrams to grams (g)?

• A. 35.4 g
• B. 35.4 g
• C. 354 g
• D. 354,000 g

Correct answer: B

Rationale: To convert milligrams to grams, you need to divide by 1,000 because there are 1,000 milligrams in a gram. Therefore, 35,400 mg ÷ 1,000 = 35.4 grams. Choice A is incorrect because it does not account for the conversion from milligrams to grams. Choice C is incorrect as it incorrectly drops a zero, leading to an inaccurate conversion. Choice D is incorrect as it incorrectly multiplies instead of dividing, resulting in a significantly larger value than the correct answer.

3. Convert 3.75 liters to milliliters.

• A. 3.75 ml
• B. 375 ml
• C. 3750 ml
• D. 37.5 ml

Correct answer: C

Rationale: To convert liters to milliliters, you need to multiply by 1000 since there are 1000 milliliters in 1 liter. Therefore, 3.75 liters x 1000 = 3750 milliliters. This means that option C, 3750 ml, is the correct conversion. Choices A, B, and D are incorrect because they do not reflect the correct conversion from liters to milliliters.

4. Which metric prefix represents 10^-2?

• A. centi
• B. milli
• C. nano
• D. deci

Correct answer: A

Rationale: The metric prefix 'centi-' signifies 10^-2, denoting one-hundredth of a unit. For instance, 1 centimeter equals 0.01 of the base unit. Choice B, 'milli,' represents 10^-3, 'nano' in Choice C represents 10^-9, and 'deci' in Choice D stands for 10^-1. Therefore, the correct answer is 'centi.'

5. Convert 0.75 kilograms to grams.

• A. 75 grams
• B. 750 grams
• C. 7,500 grams
• D. 75,000 grams

Correct answer: B

Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in a kilogram. Therefore, 0.75 kilograms is equal to 0.75 x 1000 = 750 grams. Choices A, C, and D are incorrect as they incorrectly place the decimal point and do not reflect the correct conversion from kilograms to grams.
