Suppose a balloon has a maximum volume of 7.00 L. Also suppose that each time you blew into the balloon, you expelled 0.048 mol of air...?

... How many times can you blow into the balloon before the balloon pops? Assume atmospheric conditions of 1.0 atm and 22°C and that your breath is room temperature.

I tried this question and got that it would take 7 breaths to pop the balloon. But that just doesn't seem right to me. Thoughts?
