# Boyles law calculations?

i just did an online lab for Boyles Law and I'm not sure how to do the calculations because I'm not really sure what I'm supposed to calculate. I have the numbers from the lab showing the pressure increasing as the volume decreases, but what calculations would go along with that for a lab report?

here are my #'s for the first procedure I did:

-1 atm of C3H8 flushed into 150 mL flask- pressure 1.000atm

-the above with 20mL H2O added-vol:130mL gas, 20 mL water; pressure: 1.154 atm

i did 5 procedures like this, so if someone can show me hwo to do the calculations for this, i can figure out the rest on my own...thanks!

KP/V =C so Kelvins will be the same as original

-reducing the volume will raise the temperature*pressure

K=(150/130)(1.154)Koriginal .....(what was your starting temperature?)
