Molality = gram moles of Salute/mass of solute in kg.
Then, 0.30 * 1000/600 = 300.00/600 = 1/2 = 0.50 answer.

Morality is defined as,

Molality=(solute (gram)/mass of solvent in kg)
=> volume density of solution is kg/10000.

So, 600/1000= 0.600.

M=0.3 kg/0.600liter=0.30*0.600=0.50 kmol/litre.

Molality = (gmol of solute/Mass of Solvent in Kg).

So, Molality = (.3 * 1000)/600 = 0.5.

Density of water = 1000 kg/m3 {g/liter}.
Volume of solution = kg/ density.
= 600/ 1000 = 0.6 liter.
M = 0.3 kg/0.6 liter = 0.50 kg mole/ liter.

Molality=(mol of solute/Kg of solvent).

So, 0.30 kg mol=0.30*1000 mol= 300 mol,
Hence, Molality = 300mol/600Kg=0.5 mol/Kg.

Molality = (kg solute/kg solvent)*100.
= (.3/600)*1000.
= 0.5.
