1. Consider this item as ideal gas: A rigid tank containing 3 lb of gaseous mixture of nitrogen, helium and carbon dioxide, each 33.33 % by volume at 40 psia, and 150°F receives 1 lb more of nitrogen with the temperature remaining at 150°F. For the resulting 4lb, determine (a) the gravimetric and volume analyses, (b) the pressure and (c) the molecular weight. For the initial mixture, determine (d) Cp, (e) Cv, and, (f) R
