depends on the reaction. Is it
2C8H18 + 9O2 = 16C + 18H2O ?
If so, since you have 22.8/114 = 0.2 moles of C8H18, you will need 9/2*.2 = 0.9 moles of O2, or 28.8g
nope. So, Fix the reaction and adjust the moles of O2 needed.
How many grams of oxygen are needed to burn 22.8 grams of C8H18?
80.0 g
240. g
40.0 g
20.0 g
120. g
