Suppose that you find in a reference book that the volume of all the oceans is 1.4 x 10° km. To find the mass, you can use the density of water, also found in this reference book, but first you must convert the volume to cubic meters. What is this volume in cubic meters? Express your answer in cubic meters. > View Available Hint(s) Temglates Symbols undo redo feset keyboard shortcuts Help 1.4 x 10° km m

3 A general chemistry student found a chunk of metal in the basement of a friend's house. To figure out what it was, she used the ideas just developed in class about density. First she measured the mass of the metal to be 183.3 grams. Then she dropped the metal into a measuring cup and found that it displaced 16.0 mL of 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 Substance Density (g/mL) Water 1.00 Aluminum 2.72 Chromium 7.25 8.91 8.94 10.50 11.34 13.60 19.28 19.38 Nickel Copper Silver Lead Mercury Gold Tungsten Previous Next>

You are given the masses, in grams (g), and the volumes, in cubic centimeters (cm°), for a series of substances. Arrange them in order of increasing density. Rank from lowest density to highest density. To rank items as equivalent, overlap them.

Liquid hexane  CH3CH24CH3  will react with gaseous oxygen  O2  to produce gaseous carbon dioxide  CO2  and gaseous water  H2O . Suppose 2.6 g of hexane is mixed with 13.3 g of oxygen. Calculate the minimum mass of hexane that could be left over by the chemical reaction. Be sure your answer has the correct number of significant digits.
