A 1-m³ tank holds a two-phase liquid-vapor mixture of carbon dioxide at -17°C. The quality of the mixture is 60.0%. For saturated carbon dioxide at -17°C, V = 0.9827 x 103 m³/kg and vg = 1.756 x 10²m³/kg. Determine the masses of saturated liquid and saturated vapor, each in kg. What is the percent of the total volume occupied by saturated liquid?

Properties of Pure Substances

A substance with fixed chemical composition throughout is called a pure substance like water, air, and nitrogen. A pure substance does not have to be a single element or compound. A mixture of two or more phases of a pure substance is also a pure substance as long as the chemical composition is the same for all phases. These substances mainly have a constant/ uniform composition. The substances also have fixed boiling and melting points. A pure substance takes part in a chemical reaction to form predictable products.
