Homework Statement
This question is problem 1.3.1 from Herbert Callen's textbook in Thermodynamics, second edition.
In the answers I have the following: Mole fraction of NaCl = 0.057, molar volume =$18\times 10^{-6} m^3/mole$.One tenth of a kilogram of NaCl and 0.15 kg of sugar ($C_{12} H_{22}O_{11}$ are dissolved in 0.5 Kg of pure water. The volume of the resultant thermodynamic system is $0.55\times 10^{-3}m^3$. 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?
How did they arrive at these answers? did they multiplied the ratios with Avogadro's number?
Homework Equations
Relative mole fraction is given by: [tex]N_k/\sum_{j=1}^r N_j[/tex] if we have a mixture of $r$ substances, where this is defined as the molar fraction;
Molar volume is defined as [tex]V/\sum_{k=1}^r N_k[/tex].
The Attempt at a Solution
How do extract the moles of each substance here?
