All that glitters Homework and Review Questions

Question #1 Density is found by dividing the mass by the volume of an object Find the density if the object’s mass is 45 g and its volume is 157 cm3

Question #2 Find the mass, if the object’s volume is
45 cm3 and its density is 157 g/cm3

Question #3 Find the volume if the object’s mass is
75 g and its density is 3.2 g/cm3

Question #4 A piece of tin has a mass of g and a volume of 2.26 cm3. What is the density of tin?

Question #5 A man has 50.0 cm3 bottle completely filled with 163 g of a slimy green liquid. What is the density of the liquid?

Question #6 A piece of metal has a density of 11.3 g/cm3 and a volume of 6.7 cm3. What is the mass of this piece of metal?

Question #7 A block of wood has a volume of 6 ml and a mass of 30 g. What is the density of the block of wood in g/cm3?

Question #8 A block of substance has a length of 10 cm, a width of 5 cm, and a 4 cm height. It has a mass of 150 g. Will this substance float in water? Why?

Question #9 The density of the material is 10.9 g/cm3. what is the volume of the object if its mass is g.

Question #10 A student found a piece of silver colored metal while walking through campus. She did an experiment to try to determine whether or not the metal was silver. She determined that the mass of the sample was 14.7 grams and the volume of the sample was 1.4 mL. Is the metal silver? Explain your thinking. The density of silver is 10.5 g/mL.

Question #11 A student found a piece of silver colored metal while walking through campus. She did an experiment to try to determine whether or not the metal was silver. She determined that the mass of the sample was 3.78 grams and the volume of the sample was 1.4 mL. The density of silver is 10.5 g/mL. Is the metal silver? Explain your thinking.

Question #12 What is the density of a liquid sample if the volume is 25 mL and the mass is 20 grams? 0.8 g/mL (B) 1.3 g/mL (C) 45 g/mL (D) 500 g/mL

Question #10 The density of brass is 8.4 g/mL. If you have a sample of brass with a mass of 306 grams, what volume of brass do you have? 0.027 mL (B) 36.4 mL (C) mL (D) 2570 mL

Question #13 A metal sample has a mass of 38.9 grams. If it is pure solid iron, what should the volume be? (The density of solid iron is 7.78 g/mL.) 5.0 mL (B) 0.20 mL (C) 31.1 mL (D) There is no relationship between mass and volume.

Question #14 Calculate the mass of 65 mL of mercury. The density of mercury is 13.6 g/mL.

Question #15 The density of the material is 10.9 g/cm3. what is the volume of the object if its mass is g.

Question #16 Does a bigger piece of a gold have a different density than a smaller piece?

Question #17 Find the density of a pile of salt that is shaped as a cone. The radius of the circle is cm and the height of the cone is cm. The mass of the salt is g. Find the formula that will allow you to calculate the volume of the cone of salt  Calculate the volume of salt Calculate the density of the salt  Will the salt float or sink in pure water? Explain your answer

Question #18 In terms of density, why do some things float and some sink?

Question #19 A oil tanker is made out of steel, which is much denser than water. Yet even when the tanker is loaded with oil, it floats. In terms of density, mass and volume, explain why.
