Answer :
In this particular problem, Molality is 10.74 m.
What is the difference between molality and molarity?
Despite the fact that both terms are used to describe the concentration of solutions, molality and molarity are not synonymous. The amount of solute dissolved in a litre of solution is known as its molarity. Molarity is denoted by the capital "M," and its formula is M=(# mol SOLUTE)/. (Liters of SOLUTION).
The amount of moles of solute per kilogramme of the SOLVENT, NOT the solution, is called molality. Molality is denoted by the lower case letter "m," and its formula is m=(# mole SOLUTE) /. (Kilograms of SOLVENT).
Most of the time scientists use either molarity or molality to represent solution concentration, but MOLALITY is preferred when the temperature of the solution varies. That is because MOLALITY does not depend on temperature, (Neither number of moles of solute nor mass of solvent will be affected by changes of temperature.) while MOLARITY changes as temperature changes.
In this particular problem, Molality = 10.74 m Molarity = 6.76 M mole fraction = 0.162 40%
