# Help!! Chemistry A-Level question watch

1. "The International Space Station typically has about six astronauts on board at any one time. On average, a human being breathes out about 450dm^3 of carbon dioxide each day.

Calculate the typical number of moles of carbon dioxide breathed out per day by astronauts on the ISS."
2. As there are 6 astronauts 450 x 6 = 2700dm^3 (total amount of CO2)
Assuming RTP,
number of moles = volume/24 (when volume is in dm^3)
n = v/24
so that means, 2700/24 = n = 112.5 moles
