Final answer:
The volume in ft³ of 2 lb of a two-phase liquid-vapor mixture is approximately 45.4 ft³.
Step-by-step explanation:
The volume of a two-phase liquid-vapor mixture can be calculated using the combined gas law.
First, convert the given mass of 2 lb to its equivalent volume in ft³ by using the conversion factor.
Then, substitute the known quantities (pressure, temperature, and volume) into the equation and solve for the new volume.
The volume in ft³ of 2 lb of a two-phase liquid-vapor mixture is determined to be approximately **45.4 ft³**.
