Molarityandmolalityare both measures of the concentration of a chemical solution. Molarity is the ratio of moles to volume of the solution (mol/L) while molality is theratio of molesto the mass of the solvent (mol/kg). Most of the time, it doesn't matter which unit of concentration you ...
Molality is used when the solute and solvent interact with each other, when the temperature of the solution will change, when the solution is concentrated, or for a nonaqueous solution. You would also use molality rather than molarity when you're calculating boiling point, boiling point elevation...
A solution of aqueous substance (molar mass 90.8g/mol) has a molarity of 1.3M and density 1.08g/mL. What is its molality? What is the molality of a solution made from 5.61 moles of KCl and 2.11 kg of water? W...
The relation between mole fraction and molality is simply(26)xA=nAnA+nB=mAnBMB1000(nA+nB)=mAMBxB1000.Substituting Eq. 26 in the first equation of Eq. 23, we have(27)μA=μA0+RTlnmAMBxB1000γAxγA∞=μA,m∗+RTlnγAmmAm0,where m0 = 1 [mol/kg] was introduced to make the ...

Molarity =(% "by weight" xx "Density" xx 10)/("Molecular weight") =(13 xx 1.02 xx 10)/98 =132.6/98 =1.35 M 13% solution by weight means that 13 g of solute is dissolved in 87 g of solvent. Thus, molality =(("Weight of solute")/("Molecular weig

It can be measured in different ways such as molarity, molality, mass percent, mole fraction, etc. Answer and Explanation: Molality is defined as the number of moles of solute present in the total mass of the solvent in Kg. Its units are Molal (m) and mol/Kg. 1 molal is......
