-If ethanol (S.G. = 0.790) were used rather than water in measuring the density of the irregular objects, how would that have affected the result? Explain. -When you were measuring the volume of the irregular solid you were told to stir to eliminate bubbles. If the bubbles were not eliminated, how would that affect the density? Explain. -Suppose the density of 65.0 mL of some liquid was found to be 0.748 g/mL. What would be the specific gravity of 45.0 mL of this liquid?

A certain copper ore contains 2.32% of Cu2S by mass, and the remainder of the ore contains no copper. In a particular year, a single open-air smelt furnace heated 37000 tons of this ore. Compute the maximum mass of copper metal that could have been obtained by this process. (Clarification: The tons in this problem are English tons, with 1 ton = 2000 lb. You can answer in g, kg, or lb, but the computer does not understand tons as a unit for the answer.)
When concentrated nitric is sold, the label contains no mention of the molarity of the acid. Instead, the label normally lists the concentration of nitric acid as a wt/wt percent and gives the specific gravity of the solution. If the solution is 68.0 (wt/wt %) and nitric acid and has a specific gravity of 1.41 kg/L, calculate the molarity of 68.0 % concentrated nitric acid. FW HNO3=63.01g/mol
