Concentrated sulfuric acid (18.4 molar) has a density of 11.84 g per ml dilution with water to 5.20 molar, density of 1.38 g per ml can be used as an a electroyte is lead batterys. What is the molality of the 5.20 molar H2SO4 solution? well im not exactly sure where to start, but i know that i need to find moles of solute/kg of solvent. i think i should start with grams in one liter and use that to find the number of grams or moles of solution, but other than that i am pretty lost. where am i wrong and whats next?
