A Diamond has a density of 3.513 g/mL. The mass of diamonds is often measured in "carats", where 1 carat equals 0.200 g. What is the volume (in mL) of a 1.50-carat diamond?

What is the mass (in g) of a diamond that occupies 6.09 mL if the density of diamond is 3.51 g/mL?

An unknown object is placed on a balance, which then reads 6.122 g. Its volume is measured to be 3.39 cm³. Find the density of this object by dividing mass by volume. Express your answer in grams per cubic centimeter to the appropriate number of significant figures. g/cm³

Ethanol is a common laboratory solvent and has a density of 0.7890.789 g/mL. What is the mass, in grams, of 147147 mL of ethanol?

The density of water is 1.00 g/cm3. Express this density in lb/m3.  (1 oz = 28.34 g)

In 1999, scientists discovered a new class of black holes with masses 100 to 10,000 times the mass of our sun, but occupying less space than our moon. Suppose that one of these black holes has a mass of 8×103 suns and a radius equal to one-half the radius of our moon. What is its density in grams per cubic centimeter? The mass of the sun is 2.0×1030kg and the radius of the moon is 2.16×103mi. (Volume of a sphere =43πr3.)

In 1999, scientists discovered a new class of black holes with masses 100 to 10,000 times the mass of our sun, but occupying less space than our moon. Suppose that one of these black holes has a mass of 1×10^3 suns and a radius equal to one-half the radius of our moon. What is its density in grams per cubic centimeter? The mass of the sun is 2.0×10^30 kg and the radius of the moon is 2.16×10^3 mi (Volume of a sphere =4/3πr^3)

A chemistry student needs 35.0 mL of dimethyl sulfoxide for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the student discovers that the density of dimethyl sulfoxide is 1.10 g·cm -3 Calculate the mass of dimethyl sulfoxide the student should weigh out. Be sure your answer has the correct number of significant digits. ?
