|Volume of liquid on a Penny||Chemistry|
background [prelab assignment (5 points) due at the beginning of lab]
design / describe an experiment to determine the maximum volume of a liquid (in mL) on a penny based on the below materials
determine and compare the maximum volume (in mL) of water versus isopropyl alcohol on the heads-side of a penny - using a conversion factor relating # mL & # drops of liquid.
penny; graduated cylinder
dropper bottle with water or isopropyl alcohol
methods, data, & analysis
Content of lab report (25 points)
