Question
Answers
Explanation:
#P_(sol n) = chi_i P_0# where chi is the mole fraction of solvent and P naught is the pure solvent's vapor pressure.
#chi_(C_6H_6) = (32.8g * (mol)/(78g))/((32.8g * (mol)/(78g) + 19.5g * (mol)/(154g)) approx 0.769# is the mole fraction of benzene in our solution.
Hence,
#P_(sol n) = 0.769 * 100.84t o rr approx 77.50t o rr# is the vapor pressure of that solution given those data.
