A solution is made by dissolving 13.5 g of glucose (C_6H_12O_6) in 0.100 kg of water. What is the mass percentage of solute in this solution? What is the molarity of this solution? Assume that the density of approximately 1.00 g/mL A solution with a density of 0.876 g/mL contains 5.0 g of toluene (C_7H_8) and 225 g of benzene (C_6H_6). Calculate the molarity of the solution. A 2.5-g sample...
