How much does air weigh?

    This question is dependent upon the temperature of the air. Then, the way that you would weigh air would be to look at the weights of all of the gases that make up the air. I have found a website that lists weights of air at different temperature to better answer your question.

    Air’s weight changes depending on temperature.  Air weighs more at lower temperatures.  At 0 degrees F, air weights .08633 lb/cubic feet.  At 100 degrees F, its weight is 0.07090 lb/cubic feet.  At an extreme temperatures like 1,000 degrees F, air weighs 0.02717 lbs/cubic feet.  These weights are calculated at Standard Atmospheric Pressure.
