Question

Moles equal moles of h,o and nacl are present in a solution, hence, molality of nacl solution is

Answer 1

Answer:

If we consider the solution as not saturated then we can ignore any changes in final volume after adding NaCl , otherwise it decreases in case of saturated solution .Equal moles of h2o and nacl are present in a solution hence molality of NaCl solution is 55.55 mol/ litre .
