Question 1

How many low dose 81 mg aspirin tablets can be made from 1.21 kg of aspirin?

Accepted Answer

1.21 kg is 1,210,000 mg. Dividing by 81 mg per tablet gives approximately 14,938 tablets, which is closest to 1.5 × 10^4.

Question 2

How many cm³ are there in 2.5 m³?

Accepted Answer

1 m³ = 100 cm × 100 cm × 100 cm = 10⁶ cm³So, 2.5 m³ = 2.5 × 10⁶ cm³

Question 3

How many liters are in 333 mL?

Accepted Answer

To convert milliliters to liters, we need to divide by 1000. 
333 mL ÷ 1000 = 0.333 L

Question 4

Which term below is equivalent to one milliliter?

Accepted Answer

All of the choices are equivalent to one milliliter: 
A) 1 cc (cubic centimeter) is equivalent to 1 mL because they are both measuring volume.
B) 1 mL is already stated as equivalent to 1 milliliter. 
C) 1 cm³/s (cubic centimeter per second) is not equivalent to one milliliter because it is measuring the rate of flow or volume per unit time.

Question 5

How many milliliters are in 17.5 L?

Accepted Answer

There are 1,000 milliliters in a liter, so 17.5 liters is equal to 17.5 × 1,000 = 17,500 milliliters, which is 1.75 × 10^4 milliliters.

Question 6

How many inches are in 2.80 ft?

Accepted Answer

There are 12 inches in 1 foot. Therefore, to convert from feet to inches, you need to multiply by 12. 
2.80 ft x 12 = 33.6 inches 
So the answer is B) 33.6.

Question 7

A lead ball has a mass of 55.0 grams and a density of 11.4 g/cm³.What is the volume of the ball?

Accepted Answer

The formula for calculating volume is V = m/d, where V is volume, m is mass, and d is density. Substituting the given values, we get V = 55.0 g / 11.4 g/cm^3 = 4.82 mL. Therefore, the answer is choice C.

Question 8

Suppose a boat engine leaks 938 milliliters of oil into a lake.The mass of this spilled oil is 823 grams.The oil will not mix with the lake water.Which statement is true?

Accepted Answer

The density of the spilled oil is 0.877 g/mL, which is less than the density of water (1 g/mL). Therefore, the spilled oil will float on the surface of the water. Choice A and C can be eliminated because the density given is incorrect for the spilled oil. Choice D can also be eliminated because the density provided is for a substance denser than water, so it would sink. Therefore, the correct answer is B.

Question 9

A 12-oz can of soda pop costs fifty cents.A 2.00 L bottle of the same variety of soda pop costs $1.29.How many times more expensive it is to buy the 12-oz can of pop compared to buying it in a 2.00 L bottle? (1.00 L = 1.057 quart and 1 quart contains 32 oz)

Accepted Answer

The answer of A 12-oz can of soda pop costs...

Question 10

How many inches are in 25.8 cm?

Accepted Answer

There are 2.54 centimeters in an inch. Therefore, to convert 25.8 cm to inches, we divide 25.8 by 2.54. This gives us 10.16 which is approximately equivalent to 10.2 inches. Therefore, the correct answer is D) 10.2.

Question 11

What is the density (g/mL)of an object that has a mass of 14.01 grams and,when placed into a graduated cylinder,causes the water level to rise from 25.2 mL to 33.6 mL?

Accepted Answer

The volume of the object can be found by subtracting the initial volume of water (25.2 mL) from the final volume (33.6 mL):

33.6 mL - 25.2 mL = 8.4 mL

The density of the object can then be found by dividing its mass by its volume:

Density = mass/volume = 14.01 g/8.4 mL = 1.67 g/mL (rounded to two significant figures)

The closest choice to this answer is B, 1.7 g/mL.

Question 12

A room has dimensions of 10.0 ft × 20.0 ft × 8.00 ft.Given that there are three feet in a yard,what is the volume of the room in yd³?

Question 13

What is the volume of a cube with dimensions 11.0 cm × 11.0 cm × 11.0 cm in m³?

Accepted Answer

To convert from cm³ to m³, we need to divide by 1,000,000, since there are 1,000,000 cm³ in 1 m³.
So, the volume of the cube in m³ is (11.0 cm)³ / (100 cm)³ = 0.001331 m³
Using scientific notation, this is 1.331 × 10^-3 m³, which is equal to 1.331 × 10^3 cm³.
Therefore, the correct answer is C, 1.33 × 10^3 cm³ = 1.33 × 10^(-3) m³.

Question 14

How many grams are in 1.48 × 10⁷ μg?

Accepted Answer

The answer of How many grams are in 1.48 ×...

Question 15

Given the following list of densities,which materials would float in a molten vat of lead provided that they do not themselves melt? Densities (g/mL): lead = 11.4,glass = 2.6,gold = 19.3,charcoal = 0.57,platinum = 21.4.

Accepted Answer

Materials with densities lower than that of lead (11.4 g/mL) will float. Glass (2.6 g/mL) and charcoal (0.57 g/mL) have lower densities than lead, so they would float.

Question 16

A plastic block has dimensions of 2.2 cm × 3.0 cm × 1.5 cm and a mass of 12.4 grams.Will the block float in water and why?

Question 18

How many microliters are in 41.0 mL?

Accepted Answer

There are 1,000 microliters in a milliliter, so 41.0 mL is equal to 41.0 × 1,000 = 41,000 microliters, which is written as 4.10 × 10^4 in scientific notation.

Question 20

Given the density of Au is 19.3 g/cm³,determine the mass of gold in an ingot with the dimensions of 10.0 in × 4.00 in × 3.00 in.

Accepted Answer

The volume of the ingot is calculated by multiplying its dimensions: 10.0 in × 4.00 in × 3.00 in = 120 in³. Convert this to cm³ (1 in = 2.54 cm), so 120 in³ = 1965.12 cm³. Multiply by the density of gold (19.3 g/cm³) to find the mass: 1965.12 cm³ × 19.3 g/cm³ = 3.80 × 10⁴ g.
