We will use the direct formula for converting the percent mass(%) to molarity using density.We know that molality basically means moles per 1 kg of the solvent. So we will somehow calculate the mass of the solution and from that, we will calculate the percent mass of the solute. All we have to do is to find the mass of solute(g) in 100g of solutionPercent by mass of barium bromide in the solution is -6.81%The molarity of potassium bromide in the solution is -4.60 M
