Explanation / Answer

we have 16.39% of eugenol so we have 100 - 16.39 = 83.61 % water

now apply daltons law of pressure

Total pressure is 744 torr

P total = P eugenol + P water

744.6 = 0.1639 * P eugenol + 760 * 0.8361

744.6 = 0.1639 P eug + 635.436

744.6 - 635.436 = 0.1639 P eug = 109.164

P eug = 109.164 / 0.1639 = 666.04 torrs

in steam distillatin the pressure of the mixture equals the atmospheric (or a given) pressure that is why the daltons law is helpful in this kind of problems
