Chemistry

I'm doing a lab in chemistry and I need help with a question, here is my data:
Mass Before: 26.4 g
After burned: 26.25 g
Total Mass burned: .15 g

1. Calculate the mass of oxygen that was consumed while the candle burned.

I think I need to use mole equations and that kind of stuff but I just don't know how to set up the equation, please help.
