A general chemistry student found a chunk of metal in the basement of a friend's house. To figure class about density. First he measured the mass of the metal to be 133.2 grams. Then he dropped the metal into a mea water. Calculate the density of the metal. Density: g/mL Use the table below to decide the identity of the metal. This metal is most likely Densities of Some Common Substances
The density of a metal is 8.67 g/cm. How many pounds are in 298.86 in of the metal? (You can use the conversion factor approach. Or, you can convert density in g/cm? to Ib/in and then thultiply the result times number of pounds. 2.52 cm 1 inch 454 g = 1 lb Please see 'answers to extra problems' question 10 for hints on how to do this.) You need to write your answer in the box with one number past the decimal. Please don't worry about the sig figs in this case. In these formula problems, the Canvas software will give a variety of questions and each student gets their data with different sig figs. So I just have to choose and sometimes it might seem that one past the decimal is not the correct sig figs. Nonetheless, you have to follow that direction.
Express each result in correct number of significant figures and with correct unit.
