Molality is expressed as moles solute/kg solvent. Moles of solute = 2. Kg solvent = 6.Molality = 2 moles/6 kg = 0.33 molal

The density of LPG depends on the mix between butane and propane. Liquid butane is about 0.6 SG and propane about 0.5 SG (specific gravity). If you take the mean 0.55 SG this means 1.8 liters of liquid will give 1 kg of gas.

molality = moles solute/kg solvent moles solute = 38.0g x 1 mol/342 g = 0.111 moles kg solvent = 175 g x 1kg/1000g = 0.175 kg molality = 0.111 moles/0.175 kg = 0.635 m
