all right, im glad i found someone can help me!

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?

It's a long time since I've studied any chemistry, and so I'm rather rusty on calculations. I think it's best if I leave this one for someone else to help you with!
