moles of isopropyl alcohol = 142/60.01 = 2.36moles

moles of water = 58/18 = 3.22moles

For isopropyl alcohol C3H7OH


"\\frac{2.36 moles C_3H_7OH}{2.36 moles C_3H_7OH+3.22 moles H_2O}" = 0.423


For water


"\\frac{3.22 moles H_2O}{2.36 moles C_3H_7OH+3.22 moles of H_2O}" = 0.577


Mole fraction of C3H7OH is 0.423 and H2O is 0.577
