Amixture of methanol (methyl alcohol) and water contains 70.00 % water by mass. collapse question part ideal specific gravity incorrect answer. check precision of calculations. remember that the composition specification is in wt%. the specific gravity of water at 20°c is about 0.9982; the specific gravity of methanol at 20°c is about 0.7917. assuming volume additivity of the components, estimate the specific gravity of the mixture at 20°c. sg = entry field with incorrect answer now contains modified data 0.93625 what volume of this mixture is required to provide 150.0 mol of methanol? entry field with incorrect answer now contains modified data liters

One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(ii) carbonate, in concentrated sulfuric acid. the sulfuric acid reacts with the copper(ii) carbonate to produce a blue solution of copper(ii) sulfate. scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: (s) (aq) (s) (aq) suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. he adds powdered iron to a copper(ii) sulfate sample from the plant until no more copper will precipitate. he then washes, dries, and weighs the precipitate, and finds that it has a mass of .
