Use the following table to determine which of the other materials from the list would float if placed in a container of ethyl alcohol. concrete 2,500 ethyl alcohol 791 gold 19,300 ice 917 lead 11,340 Styrofoam 37

Step 1
If the material's density is less than the liquid's density, it will float. If it's more, it will sink. The density of ethyl alcohol is 791 kg/m^3. From the table, we can see that the densities of concrete (2,500 kg/m^3), gold (19,300 kg/m^3), and lead (11,340 Show more…

You can figure out whether a solid floats or sinks if you know its density and the density of the liquid. In which of the liquids listed below will high-density polyethylene (HDPE) float? (HDPE, a common plastic, has a density of $0.97 \mathrm{g} / \mathrm{cm}^{3} .$ It does not dissolve in any of these liquids.) $$\begin{array}{lcc} \text { Substance } & \text { Density }\left(\mathrm{g} / \mathrm{cm}^{3}\right) & \text { Properties, Uses } \\ \hline \text { Ethylene } & 1.1088 & \text { Toxic; major component of } \\ \text { glycol } & & \text { automobile antifreeze } \\ \text { Water } & 0.9997 & \\ \text { Ethanol } & 0.7893 & \text { Alcohol in alcoholic beverages } \\ \text { Methanol } & 0.7914 & \text { Toxic; gasoline additive to } \\ & & \text { prevent gas line freezing } \\ \text { Acetic acid } & 1.0492 & \text { Component of vinegar } \\ \text { Glycerol } & 1.2613 & \text { Solvent used in home care } \\ & & \text { products } \\ \hline \end{array}$$
