Mole concept lab

  1. 1. Name(s): __________________________________________ Date: _____________ Per: __________ Mole Concept LabThe purpose of this lab is to practice and reinforce the idea of the mole concept. In addition, you willdetermine the number of moles and molecules in a mouthful of water and a bite of a cookie.Part IProcedure: Fill a paper cup with water (punch) and determine the mass. Drink one mouthful of punch.Reweigh the paper cup and punch.Data:1. Mass of cup and punch initially ____________2. Mass of cup and punch after drinking a mouthful _____________3. Mass of punch swallowed ____________Calculations. Show all work and label your answers!1. Calculate the molar mass of water (punch = H2O).2. Calculate the moles of water swallowed.3. Calculate the molecules of water swallowed.4. Calculate the volume of water (punch) you swallowed. (density of water =1.0g/mL;d=m/v)Part IIProcedure:Weigh a cookie. Take an average bite of the cookie and reweigh it. Now you may eat all the cookie!Data:1. Mass of cookie __________2. Mass of cookie after eating a bite ____________3. Mass of cookie digested _______________Calculations: Show all work and label your answers!1. Calculate the molar mass of the cookie (C6H12O6).2. Calculate the moles of cookie digested.3. Calculate the molecules of cookie digested.4. Calculate the moles of cookie remaining.5. Calculate the molecules of cookie remaining.6. How many cookies are in 10 moles of cookie?
