Asolution of h2so4(aq) with a molal concentration of 3.97 m has a density of 1.216 g/ml. what is the molar concentration of this solution?

Molar Concentration of the solution is 3.475M

Explanation:

In order to calculate Molarity from Molality we must clarify its meaning

In this case, we were giving the Molality (m)= 3.97 moles H2SO4/ 1 Kg of H20.

When calculating Molarity (M), we need moles of solute that is already contained in the molality and we need Liters of solution that we can calculate like this:

Now, let´s calculate the mass solute,:

3.97moles H2SO4 x (98.08g H2SO4 /1mol H2SO4) = 389.4g H2SO4

When having the mass of the solution, now we can use the density of the solution to discovery the volumen of the solution.

Finally, we have the correct values for calculating our molar concentration.

i think its 100.

hope this !
