It relates the no. of moles of solute to the per litre of the solution, just like normality. Mole fraction of a solute is simply defined as the ratio of the number of moles of the solute divided by the total number of moles present in the solution. WebA solution is prepared by mixing 1.00 g ethanol (C₂H₅OH) with 100.0 g water to give a final volume of 101 mL. Calculate the molarity, mass %, mole fraction, and molality of ethanol in this solution. molarity: find moles of ethanol (46.07 g/mol)=2.17*10⁻² mol, total volume in L=0.101 L. moles/volume→2.17*10⁻²mol/0.101 L=0.215 M. male body type calculator
