Homework Help: Chemistry

Posted by Mary on Friday, October 30, 2009 at 8:34pm.

When we breathe we inhale oxygen, O2, and exhale carbon dioxide, CO2, plus water vapor, H2O. Which likely has more mass, the air that we inhale or the same volume of air we exhale? Does breathing cause you to lose or gain weight?

I thought that the air we breathe out has more mass since the water vapor has more mass than the CO2 and O2 gasses. This should cause me to lose weight as I lose water. Is this right? Or am I missing something? Thanks.
