1. What is 0.5 liter in ounces?

• A. 16.91 oz
• B. 15.91 oz
• C. 17.91 oz
• D. 18.91 oz

Correct answer: A

Rationale: To convert liters to ounces, you need to multiply the liter value by 33.814. Therefore, to convert 0.5 liters to ounces, you would calculate 0.5 x 33.814 = 16.91 ounces. This conversion factor is commonly used in cooking and liquid measurements. Choice B, C, and D are incorrect as they do not reflect the accurate conversion from liters to ounces.

2. Convert 0.0345 kilograms to grams (g).

• A. 3.45 grams
• B. 34.5 grams
• C. 345 grams
• D. 3450 grams

Correct answer: B

Rationale: To convert kilograms to grams, you need to multiply by 1,000 since 1 kilogram is equal to 1,000 grams. Therefore, 0.0345 kg multiplied by 1,000 equals 34.5 grams. Choices A, C, and D are incorrect because they do not correctly convert kilograms to grams. A states 3.45 grams, which is off by a factor of 10. C and D overestimate the conversion by considering the decimal point in the original value as a whole number. Hence, the correct answer is B, 34.5 grams.

3. 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.

4. What is 0.5 liters in milliliters?

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

Correct answer: B

Rationale: 0.5 liters is equivalent to 500 milliliters. To convert liters to milliliters, you multiply by 1000 since 1 liter equals 1000 milliliters. Therefore, the correct answer is 500 ml (0.5 * 1000 = 500). Choices A, C, and D are incorrect because they do not correctly convert 0.5 liters to milliliters.

5. Convert 0.07 to a fraction.

• A. 7/100
• B. 1/10
• C. 1/20
• D. 1/50

Correct answer: A

Rationale: To convert 0.07 to a fraction, we note that 0.07 is equivalent to 7/100. This is because 0.07 can be read as 7 hundredths. Thus, the correct fraction form is 7/100. Choices B, C, and D are incorrect. Choice B, 1/10, is the fraction equivalent to 0.1, not 0.07. Choice C, 1/20, and Choice D, 1/50, are also incorrect as they do not represent the value of 0.07 when converted to a fraction.
