We want to convert 55 g of solid water at -11 C to vapor at 110 C. The energy need for this process is supplied by combustion of CH./C2H6 gas mixture which is composed of 60 % CH2(g) by mass. What is the volume (as liters) of required amount of the mixture at 25 C and under 745 mmHg pressure? For water c(solid) = 2.11 Jg="K",c(liquid) = 4.18 J g Kc(gas) = 2.00 Jg 'K AH(fusion) = 6.00 kJ mol"), AH(vapor.) = 40.7 kJ mol ! For CHA AH(combustion) = -891 kJ mol" for C2H6 AH(combustion) = -1560 kJ mol = = =
