thermodynamic system

One tenth of a kilogram of NaCl and 0.15 kg of sugar (C12H22O11) are dissolved in 0.50 kg of pure water. The volume of the resultant thermodynamic system is 0.55 X 10·3 m3. What are the mole numbers of the three components of the system? What are the mole fractions? What is the molar volume of the system? It is sufficient to carry the calculations only to two significant figures.
