Question 1

How many liters of wine can be held in a wine barrel whose capacity is 26.0 gal? 1 gal = 4 qt = 3,7854 L.

Accepted Answer

To convert gallons to liters, we use the conversion factor 1 gal = 3.7854 L. 
So, we can find the number of liters in the wine barrel by multiplying its capacity in gallons by the conversion factor:
26.0 gal x 3.7854 L/gal = 98.4 L 
Therefore, the answer is C.

Accepted Answer

The volume of the metal can be calculated using the formula: Volume = Mass / Density. Substituting the given values, Volume = 63.4 g / 12.86 g/cm³ = 4.93 cm³.

Question 6

What decimal power does the abbreviation pico represent?

Accepted Answer

Pico represents 1 × 10^-12 in the International System of Units (SI).

Question 7

How many liters of air are in a room that measures 10.0 ft x 11.0 ft and has an 8.00 ft ceiling? 1 in. = 2.54 cm (exactly); 1 L = 10³ cm³

Accepted Answer

First, calculate the volume in cubic feet: 10.0 ft x 11.0 ft x 8.0 ft = 880 ft³. Convert cubic feet to cubic inches (1 ft = 12 in): 880 ft³ x (12 in/ft)³ = 1,518,720 in³. Convert cubic inches to cubic centimeters (1 in = 2.54 cm): 1,518,720 in³ x (2.54 cm/in)³ = 24,883,200 cm³. Convert cubic centimeters to liters (1 L = 10³ cm³): 24,883,200 cm³ / 10³ = 24,883.2 L, which is approximately 2.49 × 10⁴ L.

Question 8

The density of silver is 10.5 g/cm³. A piece of silver that occupies a volume of 63.1 cm³ would have a mass of __________ g.

Accepted Answer

The density of silver is 10.5 g/cm³, which means that for every cubic centimeter of silver, there are 10.5 grams of silver. To find the mass of a piece of silver that occupies a volume of 63.1 cm³, we can use the formula:mass = density × volumemass = 10.5 g/cm³ × 63.1 cm³mass = 663.15 gTherefore, the mass of the piece of silver is 663.15 g, which is closest to choice A, 663 g.

Question 9

How many significant figures are in the measurement 5.34 g?

Accepted Answer

The measurement 5.34 g has three significant figures: 5, 3, and 4.

Question 10

The density of silver is 10.5 g/cm³. A piece of silver with a mass of 125 g would occupy a volume of __________ cm³.

Accepted Answer

The volume of the silver can be calculated using the formula: Volume = Mass / Density. So, Volume = 125 g / 10.5 g/cm³ = 11.9 cm³.

Question 11

The density of air under ordinary conditions at 25 °C is 1.19 g/L. How many kilograms of air are in a room that measures 11.0 ft x 11.0 ft and has an 10.0 ft ceiling? 1 in. = 2.54 cm (exactly); 1 L = 10³ cm³

Question 15

The recommended adult dose of Elixophyllin  , a drug used to treat asthma, is 6.00 mg/kg of body mass. Calculate the dose in milligrams for a 115-lb person. 1 lb = 453.59 g.

Accepted Answer

First, we need to convert the weight of the person from pounds to kilograms.

115 lb ÷ 2.205 lb/kg = 52.16 kg

Then, we can use the recommended dose of 6.00 mg/kg to calculate the dose for this person.

Dose = 6.00 mg/kg × 52.16 kg = 313 mg

Therefore, the answer is D) 313.

Question 16

Round the following number to four significant figures and express the result in standard exponential notation: 229.613

Accepted Answer

To round to four significant figures, we start counting from the leftmost non-zero digit, which is the first "2". We then count three more digits, which are "2", "9", and "6". The fourth significant figure is "6". Since the next digit, "1", is less than 5, we leave the 6 unchanged. Therefore, the rounded number is 2.296. To express it in standard exponential notation, we move the decimal point to the right until there is only one non-zero digit to the left of the decimal point, and count the number of places we moved the decimal point. In this case, we move the decimal point one place to the right, and get 2.296 × 10^2, which is equivalent to 229.6. However, since the question asks us to express the result in standard exponential notation, the correct answer is D.

Question 17

The estimated costs for remodelling the interior of an apartment are: three 1-gallon cans of paint at $13.22 each, two paint brushes at $9.53 each, and $135 for a helper. The total estimated cost with the appropriate significant figures is

Accepted Answer

The total cost can be calculated as follows:
3 cans of paint = 3 x $13.22 = $39.66
2 paint brushes = 2 x $9.53 = $19.06
Helper = $135
Total = $39.66 + $19.06 + $135 = $193.72
Since we need to express the answer with appropriate significant figures, we should round it to two decimal places, which gives us $194. Therefore, the best choice is C.

Question 18

Accepted Answer

The answer of Gases do not have a fixed __________...

Question 19

A temperature of 300. K is the same as __________°F.
