I am working on a Chemistry lab write up and I have to determine the pressure of the dry butane gas.

My Data Table:
initial mass of lighter= 21.03g
volume of gas collected= 93.6 mL
temperature of the water= 23.2 degrees C
barometric pressure= 1.012 atm
final mass of lighter= 20.820

therefore the mass of butane collected in gas collection tube= .210g

I tried using the ratio 1/760 = x/769 ... to no avail.
