How many grams of co(g) are there in 74.5 ml of the gas at 0.933 atm and 30o c?

Nonpoint source pollution is difficult to control because it

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.
