Question

A solution of H2SO4(aq) with a molal concentration of 1.66 m has a density of 1.104 g/mL. What is the molar concentration of this solution?

Answer 1

I am having trouble figure out what 2 masses to add together.

Answer 2

H2SO4 is 98.08 g/mole

Answer 3

mass of solute (H2SO4) = morality x kg of solvent x molar mass of solute
morality = 1.66 m
molar mass of H2SO4 =98.08 g/mole

mass of solvent = mass of solution - mass of solute

Answer 4

im still confused.

Answer 5

ok, so finding Molarity, you need to find the mass mass of H2SO4, the molar mass, and the L of solution

Molarity = (mass of H2SO4 / molar mass of H2SO4) / L of solution

Answer 6

Do you know how to find the mass of 1.66 mole H2SO4 ?

Answer 7

i think so

Answer 8

chemistry confuses me a bit but i'll try to help

Answer 9

i have been good at it but i cant remember what i learned last semester.

Answer 10

I think I am good thanks. I got a friend here at school who can help me thanks.

Answer 11

ok that's great, really sorry for not understanding >.<
