15kg is 15000g. 15000/58.12 = 258.087 moles.
1 kg NaCl contain 17,112 moles.

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
1 kg of difluorodichloromethane is equivalent to 8,27 moles.
12,4439 kg of gold contain 63,177 moles.
2.70 m = 2.70 moles/kg solvent3250 g solvent = 3.25 kg solvent2.70 moles/kg x 3.25 kg = 8.775 moles NaNO3 = 8.78 moles NaNO3 (3 significant figures)
The answer is 30,151 kg.
