Answer to Question 1

Answer: It would weigh 106 pounds, because specific gravity is the ratio of a mineral's density to the density of water, which is 1.0 gram per cubic centimeter. So 5 gallons of quartz would weigh 2.65 times as much as 5 gallons of water. 40 times 2.65 is 106.

Answer to Question 2

Answer: Minerals are (1) naturally occurring (2) inorganic (3) solids that (4) possess an orderly crystalline structure and (5) a characteristic chemical composition. Gold is a mineral; seawater isn't because it isn't solid; quartz is; cubic zirconia isn't because it's not naturally occurring; obsidian isn't because it lacks an orderly crystalline structure; ruby is; glacial ice is; and amber is not because it lacks an orderly crystalline structure.
