How To Find Mole Fraction From Molarity And Density How To Calculate The Mole Fraction And Density As Well As Molality?

How to calculate the mole fraction and density as well as molality? - how to find mole fraction from molarity and density

Phosphoric acid solution was prepared by dissolving 10.0 g of H3PO4 in 100.0 ml of water. The resulting volume was 104 ml, calculate the density, mole fraction, normality and molality of the solution. Let us assume that the water has a density of 1.00g/cm ^ 3

I molarity. and partially molality. I have the right answer, but I do not think that the way forward. I am confused by the density and the same mole fraction. Thank you.
