Continue considering an ideal solution of DMF in water. Assume that $60$ g of water is mixed with $40$ g of DMF$.$ Assume that the Antoine equation given for DMF in NIST Chemistry webbook remains valid up to at least $110$ oC$,$ and assume that the prepared water$/$DMF solution is in equilibrium with its saturated vapor at $1$ bar and at $106$ oC$.$ What will be the mole fraction of DMF in the vapor above the solution?

determine number of moles of liquid present at $1$ bar and at $106$ oC$.$
