You weigh a graduated cylinder to be 58.248 grams when it is empty. You then add some unknown liquid and determine the volume of liquid to be 11.31 mL based on the marking on the graduated cylinder. You then weigh it again to find a total mass of 68.466 grams. What is the density of the unknown substance, based on these measurements? Give you answer in decimal format.

You want to determine the density of a metallic solid object. The object weighs 144.38 grams. You a graduated cylinder where the water level is at 22.0 mL. The water level rises to 29.1l mL when you the cylinder. Calculate the density of the metal cylinder. 6. Mass of object = 7. Volume of object = 8. Density of object =

A student was given an unknown metal.  The student determined that the mass of the metal was 30.2 g.  The student placed the metal in a graduated cylinder filled with 20.0 mL of water.  The metal increased the volume of water to 22.9 mL.  Calculate the density of the metal and determine the identity of the metal using the table below.

How many significant figures should your result contain? What is the calculated density? Express your answer to the correct number of significant figures.

Since density depends on the mass and volume of an object, we need both of these values combined in the correct way to solve for density. Keep in mind that we may not be given the mass and volume directly, or the values may not be given in the units we want and we need to convert to the correct units before solving for density. When converting between metric units, use the prefixes to help you determine the magnitude of a value. The prefix k indicates kilo, 1000. Therefore 1000 g = 1 kg. A 17.0 kg iron weightlifting plate has a volume of 2160 cm³ . What is the density of the iron plate in g/cm³? Express your answer in grams per cubic centimeter to three significant figures. • View Available Hint(s) Hνα ΑΣφ ? density of iron plate = g/cm3

The volume of an irregular solid was determined by difference using a 100 mL graduated cylinder. The initial volume was 28.54 mL. After the solid was added to cylinder the volume reading was 50.22 mL. If the mass of the irregular solid is 35.63 g, calculate the density of the irregular solid.

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. ?

An empty graduated cylinder weighed 38.879 grams. After it was filled with 34.150 mL of a an unknown liquid substance, it weighed 60.627 grams. What is the density of the unknown substance, based on these measurements? Give you answer in decimal format. When entering units, use proper abbreviated units with proper capitalization
