A sample of sand is found to have a mass of 12.0 g and to have a volume of 2.69 cm3. What is its density in grams per cubic centimeter?

What is the mass of a 43.8-mL sample of gasoline, which has a density of 0.70 g/cm3?

Ethyl acetate, one of the compounds in nail polish remover, has a density of 0.9006 g/cm3. Calculate the volume of 25.0 g ethyl acetate.

Bromine is a red-brown liquid with a density of 3.10 g/mL. A sample of bromine weighing 88.5 g occupies what volume?

The first measurement of sea depth was made in 1840 in the central South Atlantic, where a plummet was lowered 2425 fathoms. What is this depth in meters? Note that 1 fathom = 6ft, 1 ft = 12 in., and 1 in. = 2.54 102 m. (These relations are exact.)

Providing no reaction occurs, a solid will float on any liquid that is more dense than it is. The volume of a piece of calcite weighing 35.6 g is 12.9 cm3. On which of the following liquids will the calcite float: carbon tetrachloride (density = 1.60 g/cm3), methylene bromide (density = 2.50 g/cm3), tetrabromoethane (density = 2.96 g/cm3), or methylene iodide (density = 3.33 g/cm3)?

a 7.11 hg to g, b 5.27 x 107 m to pm, c 3.63 x 106 g to dag.

The following are properties of substances. Decide whether each is a physical property or a chemical property. a Chlorine gas liquefies at 35C under normal pressure. b Hydrogen burns in chlorine gas. c Bromine melts at 7.2C. d Lithium is a soft, silvery-colored metal. e Iron rusts in an atmosphere of moist air.

A sample of vermilion-colored mineral was weighed in air, then weighed again while suspended in water. An object is buoyed up by the mass of the fluid displaced by the object. In air, the mineral weighed 18.49 g; in water, it weighed 16.21 g. The densities of air and water are 1.205 g/L and 0.9982 g/cm3, respectively. What is the density of the mineral?
