It is difficult to imagine a qualified "chemistry" teacher giving a problem such as this.
Water content varies from 45 to 71 percent of body mass, depending on age, gender, and percent body fat.
Here as one answer: assume the water content is 60 percent,
water= 62kg*.60*2.2lbs/kg
Yes, I'm sorry I left out the fact that it stated a typical adult body contains 51% water.
