gas laws and th molar mass of air


the gas laws test in tomorrow.
i just know that it's going to be hard
we did labs on the molar mass of butane and the molar mass of air.
a lot of calculations were involved and we had to calculate percent error for each one.
we also learned about STP (standard temperature pressure) and ideal gas laws (PV=nRT).
balloons have to do with gas laws!
this block is going to be short because i have to study for the test.
next week is spring break! thank god! but sadly, there's hw for this class :(
