🤓 Based on our data, we think this question is relevant for Professor Gladfelter's class at UMN.
Mole Fraction (X) relates the moles of each species in a mixture:
Calculate the mole fraction.
0.0300 mole of CH2Cl2
0.0500 mole of CH2Br2
XCH2Cl2 = 0.375
A solution is prepared by mixing 0.0300 mole of CH2Cl2 and 0.0500 mole of CH2Br2 at 25°C. Assuming the solution is ideal, calculate the composition of the vapor (in terms of mole fractions) at 25°C. At 25°C, the vapor pressures of pure CH2Cl2 and pure CH2Br2 are 133 and 11.4 torr, respectively.
