1. What is 0.3 ml in tsp?

• A. 0.06 tsp
• B. 0.1 tsp
• C. 0.2 tsp
• D. 0.3 tsp

Correct answer: A

Rationale: To convert milliliters to teaspoons, you can use the conversion factor that there are approximately 5 milliliters in a teaspoon. When you divide 0.3 ml by 5, you get 0.06 teaspoons, which is equivalent to 0.06 tsp. Therefore, the correct answer is A. Choice B, 0.1 tsp, is incorrect because it does not result from the conversion of 0.3 ml to tsp. Choice C, 0.2 tsp, is also incorrect as it does not accurately represent the conversion. Choice D, 0.3 tsp, is the same value as the original quantity in milliliters, which is not the correct conversion to teaspoons.

2. What is 0.1 kg in grams?

• A. 100 g
• B. 10 g
• C. 1 g
• D. 0.1 g

Correct answer: A

Rationale: To convert kilograms to grams, you need to multiply by 1,000 since there are 1,000 grams in a kilogram. Therefore, 0.1 kg equals 100 grams. Choice B (10 g) is incorrect because it represents converting 0.01 kg to grams. Choice C (1 g) is incorrect as it reflects the conversion of 0.001 kg to grams. Choice D (0.1 g) is the value in grams equivalent to 0.01 kg, not 0.1 kg.

3. 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.

4. What is the equivalent of 1 nanometer (nm) in meters (m)?

• A. 10^-9 meters
• B. 10^-6 meters
• C. 10^-12 meters
• D. 10^-15 meters

Correct answer: A

Rationale: The correct answer is A: 10^-9 meters. 1 nanometer (nm) is equivalent to 10^-9 meters. This conversion is commonly used in various scientific fields, including nanotechnology, to represent extremely small lengths. Choice B, 10^-6 meters, is incorrect as it represents a micrometer, not a nanometer. Choice C, 10^-12 meters, is incorrect as it would be a picometer, which is smaller than a nanometer. Choice D, 10^-15 meters, is incorrect as it would be a femtometer, much smaller than a nanometer.

5. What is 0.1 liter converted to milliliters?

• A. 10 ml
• B. 100 ml
• C. 1000 ml
• D. 1 ml

Correct answer: B

Rationale: To convert 0.1 liter to milliliters, you need to multiply by 1000 because there are 1000 milliliters in a liter. Therefore, 0.1 liter converts to 100 milliliters. Choice A (10 ml) is incorrect as it represents 0.01 liters, not 0.1 liters. Choice C (1000 ml) is incorrect as it represents 1 liter, not 0.1 liters. Choice D (1 ml) is incorrect as it is too small a quantity for 0.1 liters.
