13.3B In a mixture of gases, the volume percent of a gas divided by 100 times the total pressure equals the gass partial pressure (Daltons law, Section 5.4): Pgas = 0.40 × 1.2 atm = 0.48 atm. Sgas 1.2×10−2 mol/L kH = = = 2.5×10−2 mol/L·atm Pgas 0.48 atm 13.4A Convert mass (g) of ethanol to kg, multiply by the molality to obtain
