Molality = (solute/solvent) *100.
= (0.30/600) *1000.
= 0.50
= (0.30/600) *1000.
= 0.50

Base on what change from 100 to 1000
= (0.30/600) *1000.

Molality is defined as the number of moles of solute dissolved in 1 liter of solvent.
Hence, molality = (no.of solute/no.of solvent) *1000.
= (0.3/600) *1000.
= 0.50.
Hence, molality = (no.of solute/no.of solvent) *1000.
= (0.3/600) *1000.
= 0.50.

Molality = Number of grm moles of solute per kilogram of solvent.
= 0.3*1000/600=0.5m
= 0.3*1000/600=0.5m

Gram mole of solute per kilogram of solvent = Molality.

Molality is differ from molarity.
Molality is no.of moles of solute present in kg of solvent.
So Molality = (wt.of solute/molecular wt.of solute)*(1000/wt.of solvent).
Molarity is not based on wt.of solvent it based on volume.
Molarity= (wt.of solute/molecular wt.of solute)*(1000/volume of solution).
Molality of given pro is (0.3*1000) /600 = 0.5.
Molality is no.of moles of solute present in kg of solvent.
So Molality = (wt.of solute/molecular wt.of solute)*(1000/wt.of solvent).
Molarity is not based on wt.of solvent it based on volume.
Molarity= (wt.of solute/molecular wt.of solute)*(1000/volume of solution).
Molality of given pro is (0.3*1000) /600 = 0.5.

Molality = Number of gram moles of solute per kilogram of solvent.
Molality= 0.3 x 1000 / 600 = 0.5.
1 kg = 1000 gm thats why it is multiplied by 1000.
