Goals

• Practice your lab skills—specifically careful liquid measurement and gas collection under water.
• Reinforce topics in class—in this case, gas laws and partial pressure.
• Practice gas law calculations, molar mass determination, and finding percent error.

Objective

• Use a lighter to determine the molar mass of butane and compare this to the accepted value.
