A solution of 0.0400 mol of C2H4Br2 and 0.0600 mol of C3H6Br2 exerts a vapor pressure of 145.4 mm Hg — Solutions Chemistry Question

A solution of 0.0400 mol of C₂H₄Br₂ and 0.0600 mol of C₃H₆Br₂ exerts a vapor pressure of 145.4 mm Hg at a certain temperature. Determine the vapor pressure of pure C₃H₆Br₂ at this temperature. Assume the vapor pressure of C₂H₄Br₂ at this temperature is 173 mm Hg and that the solution obeys Raoult's Law.
