1. What is the term for the amount of space an object occupies?

• A. mass
• B. volume
• C. density
• D. area

Correct answer: B

Rationale: The correct term for the amount of space an object occupies is 'volume.' Volume refers to the three-dimensional space that an object occupies and is measured in cubic units like cubic meters. 'Mass' (Choice A) refers to the amount of matter in an object, 'density' (Choice C) is the mass per unit volume of a substance, and 'area' (Choice D) is the measurement of the extent of a surface.

2. The prefix giga is represented by the following notation ________.

• A. G
• B. m
• C. Gg
• D. g

Correct answer: A

Rationale: The correct answer is A: 'G'. The prefix 'giga' is commonly represented by the letter 'G' and corresponds to a factor of 10^9, which is equivalent to one billion. Choice B, 'm', represents the prefix 'milli', which corresponds to a factor of 10^-3, not 'giga'. Choice C, 'Gg', is incorrect as the prefix 'giga' is represented by a single letter 'G', not 'Gg'. Choice D, 'g', is incorrect as it represents the prefix 'gram' in the International System of Units (SI) and not the prefix 'giga'.

3. What is 0.03 as a fraction?

• A. 3/100
• B. 1/30
• C. 1/3
• D. 1/10

Correct answer: A

Rationale: To convert a decimal to a fraction, you place the decimal value over a power of 10, where the number of zeros in the denominator is equal to the number of decimal places in the decimal. In this case, 0.03 can be written as 3/100 because there are two decimal places (hundredths). This fraction is already in simplest form. Choice B, 1/30, is incorrect as it represents 0.033 as a fraction. Choice C, 1/3, is incorrect as it represents 0.3 as a fraction. Choice D, 1/10, is incorrect as it represents 0.1 as a fraction.

4. What is the equivalent of 0.3 mg in ml?

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

Correct answer: A

Rationale: The correct answer is A: 0.3 ml. To convert milligrams (mg) to milliliters (ml), you typically need the substance's density. However, in many medical contexts, especially with liquid medications similar in density to water, 0.3 mg is commonly assumed to be equivalent to 0.3 ml. Choice B (3 ml) is incorrect as it is 10 times greater than the correct conversion. Choice C (30 ml) is incorrect as it is 100 times greater than the correct conversion. Choice D (0.03 ml) is incorrect as it is one-tenth of the correct conversion.

5. 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.
