10. Bromine is a reddish-brown liquid. Calculate its density (in \( \mathrm{g} / \mathrm{mL} \) ) if \( 586 \mathrm{~g} \) of the substance occupies \( 188 \mathrm{~mL} \). (4 points) 11. Aluminum is a lightweight metal (density \( = \) \( 2.70 \mathrm{~g} / \mathrm{cm}^{3} \) ) used in aircraft construction, high-voltage transmission lines, beverage cans, and foils. What is its density in \( \mathrm{kg} / \mathrm{m}^{3} \) ? (4 points) 12. Calculate the mass of a cube of platinum of edge length \( 0.040 \mathrm{~mm} \) (the density of platinum \( \left.=21.4 \mathrm{~g} / \mathrm{cm}^{3}\right) \cdot(5 \) points \( ) \) 13. A piece of silver \( (\mathrm{Ag}) \) metal weighing \( 194.3 \) \( \mathrm{g} \) is placed in a graduated cylinder containing \( 242.0 \mathrm{~mL} \) of water. The volume of water now reads \( 260.5 \mathrm{~mL} \). From these data calculate the density of silver in units of \( \mathrm{g} / \mathrm{mL} \). (5 points) 14. Cholesterol in blood is measured in milligrams of cholesterol per deciliter of blood. If the average adult has \( 6.0 \) liters of blood, how many grams of cholesterol would 11.
