- Gold leaf, which is used for many decorative purposes, is made by hammering pure gold into very thin sheets. Assuming that a sheet of gold leaf is 1.27 105 cm thick, how many square feet of gold leaf could be obtained from 28.35 g gold? The density of gold is 19.3 g/cm3.arrow_forwardAlthough the preferred SI unit of area is the square meter, land is often measured in the metric system in hectares (ha). One hectare is equal to 10,000 m2. In the English system, land is often measured in acres (1 acre = 160 rod2). Use the exact conversions and those given in Exercise 47 to calculate the following. a. 1 ha = __________ km2 b. The area of a 5.5-acre plot of land in hectares, square meters, and square kilometers c. A lot with dimensions 120 ft by 75 ft is to be sold for 6500. What is the price per acre? What is the price per hectare?arrow_forwardWhat is the difference in surface area between two circles, one of radius 7.98 cm, the other of radius 8.50 cm? The surface area of a circle of radius r is r2. Obtain the result to the correct number of significant figures.arrow_forward
- Providing no reaction occurs, a solid will float on any liquid that is more dense than it is. The volume of a piece of calcite weighing 35.6 g is 12.9 cm3. On which of the following liquids will the calcite float: carbon tetrachloride (density = 1.60 g/cm3), methylene bromide (density = 2.50 g/cm3), tetrabromoethane (density = 2.96 g/cm3), or methylene iodide (density = 3.33 g/cm3)?arrow_forwardWhat is the mass of a 1.75 L sample of a liquid that has a density of 0.921 g/mL?a) 1.61 * 103 g b) 1.61 * 10 - 3 gc) 1.90 * 103 g d) 1.90 * 10 - 3 garrow_forwardThe length of a 262 mm line can also be expressed as: (choose one of the choices) Hint: you must look at answer choices and determine which ones are wrong.
