I was given three questions in my Gen Chem I class, but I am not sure how to solve them. Can someone please explain how to solve these problems?
1. A sheet of zinc foil has a total area of 1.00 ft² and a mass of 8.64 grams. What is the thickness of the foil in millimeters? (Density of zinc = 7.13 g/cm³)
2. The total volume of seawater in the world's oceans is 1.5 x 10²¹ L. Assume that seawater contains 3.1% sodium chloride by mass and that seawater has a density of 1.03 g/mL. Calculate the total mass of sodium chloride in kilograms (kg) and in tons. (1 ton = 2,000 pounds, 1 pound = 453.6 grams)
3. Vanillin is the substance whose aroma the human nose detects in the smallest amount. The threshold limit is 2.0 x 10⁻¹¹ g per liter of air. If the current price of 50.0 g of vanillin is $21.65, determine the cost to supply enough vanillin so that the aroma could be detected in Wembley Stadium (volume = 2.6 x 10⁹ ft³).
