8Question #7A 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?
9Question #8A 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?
10Question #9The density of the material is 10.9 g/cm3. what is the volume of the object if its mass is g.
11Question #10A 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.
12Question #11A 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.
