How do you convert 19.32 g/cm^3 to final units of volume?

A chemist must dilute 53.1 mL of 4.27 M aqueous calcium bromide (CaBr₂) solution until the concentration falls to 2.00 M. She'll do this by adding distilled water to the solution until it reaches a certain final volume. Calculate this final volume, in liters. Be sure your answer has the correct number of significant digits. ☐ 4× 10 L S ? x10 X

Unit Conversion: 3.05 × 10−1 s to ms

the radius of a neon atom is 6.9 x 10 ^-2 nm, and its mass is 3.35 x 10^-17 micrograms. what is the density of the atom in grams per cubic inch (g/in^3) ?

If a sample of unknown substance has a mass of 3.50 kg and a volume of 1.30 L, what is the density of the substance when expressed in conventional (but non-SI) units of g/cm3?

A solution of 5.00% glucose (C6,H12,O6) solution is used in many medical settings. If you are given 75.0 g of this solution, how many grams of glucose did you receive? Write the value to the correct significant figures.

In some polluted city air the amount of lead was measured at 3.1 x 10^-6 g/m^3. What is the amount of lead in nanograms per cubic centimeter

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 thief plans to steal a gold sphere with a radius of 28.4 cm from a museum. If the gold has a density of 19.3 g/cm^3, what is the mass of the sphere in pounds? [The volume of a sphere is V=(4/3)πr^3]. Express your answer in pounds to 3 significant figures.
