In an earlier chapter, we described the development of the atomic mass unit, the concept of average atomic masses, and the use of chemical formulas to represent the elemental makeup of substances. These ideas can be extended to calculate theformula massof a substance by summing the average ato...
Calculate the molarity and mole fraction of acetone in a 1.00-m solution of acetone (CH_3COCH_3) in ethanol (C_2H_3OH). (Density of acetone = 0.788 g/cm^3; density of ethanol = 0.789 g/cm^3.) Assume t A solution of 0.2113 g of water dissolved in 25.0 g of a solvent...
