The molecules are continually colliding with each other and with the walls of the container. When a molecule collides with the wall, they exert small force on the wall The pressure exerted by the gas is due to the sum of all these collision forces. The more particles that hit the walls, the higher the pressure.
I think it would be useful because then a gas station would have to save gas, instead of selling it all. But, for this question Im not to sure. Is this a multiple choice question_
if 105 grams burns completely
therefore
105 ×22.4/48=49
I believe its hydrogen and carbon dioxide.
