CH4 + 2O2 --> 2H2O + CO2 How many moles of water can be formed from 3.4 moles of CH4 and 3.4 moles of O2?

The size (radius) of an oxygen molecule is about 2.0 ×10−10m. make a rough estimate of the pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior at ordinary temperatures (t= 300k ). assume that deviatons would be noticeable when volume of the gas per molecule equals the volume of the molecule itself.
