Question

please tell me the molality of the solution.....tell me only. the 2nd part not the first part....please

Answer 1

Answer:

Explanation:

MASS OF SOLUTE(SUGAR)= 50 G

MASS OF SOLVENT(WATER)= 100 G

MOLECULAR/MOLAR MASS OF SUGAR=C12H22O11

                          = 12*12+1*22+16*11                [C= 12 G,H=1 G, O=16 G]

                          =144+22+176

                          =342 G

MOLALITY=( GIVEN MASS OF SOLUTE* 1000)

                    --------------------------------------------------

                     MOLAR MASS OF SOLUTE* MASS OF SOLVENT IN G

MOLALITY=50*1000/342*100

MOLALITY=1.461
