Can never be a value for a mole fraction

WebTo use Raoult’s law to calculate the vapor pressure of the solution, we must know the mole fraction of water. Thus we must first calculate the number of moles of both ethylene glycol (EG) and water present: moles EG = (302 g) (1 mol 62. 07 g) = 4. 87 mol EG moles H 2 O = (698 g) (1 mol 18.02 g) = 38.7 mol H 2 O. The mole fraction of water is thus WebUse the gas constant that will give K_\text p K p for partial pressure units of bar. To solve this problem, we can use the relationship between the two equilibrium constants: K_\text p = K_\text c (\text {RT})^ {\Delta \text n} K …
