Chapter 1, Problem 1.90AE

If a monolayer of stearic acid has a mass of 2.5*10^-5 g and occupies a surface area of 82 cm^2, what is the height of the monolayer, in cm? The density of stearic acid is 0.839 g/cm^3.

Lead has a density of 11.34 g/cm^3 and oxygen has a density of 1.31 x 10^-3 g/cm^3 at room temperature. How many cm^3 are occupied by 1g of lead? By 1 g of oxygen? Comment on the difference in volume for the two elements. The Kohinoor Diamond ( d= 3.51 g/cm^3) is 108 carats. If one carat hasa mass of 2.00 x 10^3 mg , what is the mass of the Kohinoor Diamond in pounds? What is the volume of the diamond in cubic Inches? A waterbed filled with water has the dimensions 8.0 ft x 7.0 ft x 0.75 ft. Taking the density of water to be 1.00 g/cm^3,how many kilograms of water are required to fill the waterbed? Vinegar contains 5.00% acetic acid by mass and has a density of 1.01 g/mL. What mass(in grams) of acetic acid is present in 5.00 L of vinegar?

Gold is alloyed (mixed) with other metals to increase its hardness in making jewellery. Consider a piece of gold jewellery that weighs 12.0 g and has a volume of 0.675 cm3. The jewellery contains only gold and silver, which have densities of 19.3 g/cm3 and 10.5 g/cm3, respectively. Assuming that the total volume of the jewellery is the sum of the volumes of the gold and silver that it contains, calculate the percentage of gold (by mass) in the jewellery.
