Ethane - Density and Specific Weight vs. Temperature and Pressure

Calculate and display the density and specific weight of ethane at varying temperatures and pressures. Density (ρ) is defined as the ratio of mass to volume, typically measured in kg/m³ or lb/ft³. Specific weight (γ) is the ratio of weight to volume, typically measured in N/m³ or lbf/ft³, and equals ρ × g where g is gravitational acceleration.
