Solution. 3) Concentrated sulfuric acid has a density of 1.84 g/mL and is 95.0% by mass 10.0!!!!"!"! The basic measurement of concentration in chemistry is molarity or the number of moles of solute per liter of solvent. Please visit using a browser with javascript enabled. Solution: 8.010 m means 8.010 mol / 1 kg of solvent 8.010 mol times 98.0768 g/mol = 785.6 g of solute 785.6 g + 1000 g = 1785.6 g total for solute and solvent in the 8.010 m solution. You have not finished your quiz. The ratio is then multiplied by one hundred. Also, this page requires javascript. Problem #1: A solution of H 2 SO 4 with a molal concentration of 8.010 m has a density of 1.354 g/mL.
