Identify the conversion units necessary to convert the following imperial units to metric units: qt to cm³.

Sunlight has a power density of 2.0 kW/m² in a sunny location. This can be converted by photovoltaic solar cells into electricity with 23% efficiency. Calculate the square meter of solar cells needed to meet the energy requirement of a typical home that uses 467 kWh of electricity per month. (Assume that electricity can be generated from the sunlight for 7.5 hours per day)

How many cesium atoms are needed to line up with one another to form a square grid on a 1.00 mm by 1.00 mm square surface if the diameter of a cesium atom is 0.267 nm?

The recommended acetaminophen suspension dosage for infants is 14 mg/kg body weight. If an acetaminophen suspension contains 70 mg/0.67 mL, how much should be given to a 12 lb infant? (Assume two significant figures)

In an experiment, you combine water (d = 1.00 g/mL) and hexane (d = 0.66 g/mL) in a beaker to make a mixture with a total volume of 354.4 mL and a total mass of 312.9 g.  Water and hexane do not mix. Calculate the volume of water and hexane in the mixture.

Arrange the following from smallest to largest assuming that each cube has the same mass.

Silver cube (10.49 g/cm³)

Iron cube (7.874 g/cm³)

Copper cube (8.96 g/cm³)

The density of ethanol is 0.789 g/mL.

Part A. Calculate the mass of 15.78 mL of ethanol. Express your answer to four significant figures and include the appropriate units. 

Part B. Calculate the volume of 5.63 g of ethanol. Express your answer to four significant figures and include the appropriate units. 

Persimmon wood is extremely hard, dense, and wear-resistant. It is used for making musical instruments, tool handles, flooring, and furniture. A sphere of persimmon wood has a diameter of 8.32 cm and a mass of 234 g. 

(a) Calculate the density of the persimmon sphere. 

(b) Determine whether the sphere would float in water. 

(c) Determine whether the sphere will float in petroleum ether (density = 0.653 g/mL).

Three identical spheres are made up of iron, palladium, and titanium with the following densities 7.87 g/cm³, 11.9 g/cm³, and 4.51 g/cm³, respectively. Arrange the spheres in order of increasing mass.

The American Silver Eagle is the official silver bullion coin of the United States. It has a diameter of 40.6 mm and a thickness of 2.98 mm. Silver has a density is 10.49 g/cm³ and is valued at $ 365.90/lb.

Assuming that the coin has a uniform thickness and is made of pure silver, calculate the value of the coin. 

A block of solid that weights 58.16 g was placed in a container with a 100 mL capacity. It was then filled to capacity with the liquid benzene and measured to have a combined weight of 96.15 g. 

Calculate the density of the solid if the density of benzene is 0.864 g/mL.
