Conductivity of solutions

You can add the parabolic part onto the graph on the website, so in answer to your question... both!

It really depends how advanced your class is, but since you mentioned the "supercooling" then you should draw it on.

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!

Well, I guess you already have! Here's the link to the question, for anyone that's reading through this thread: Molarity
