Answer:
Water lost per day will be "378 g".
Explanation:
The volume of air expired per a day will be:
= [tex]12\times 500[/tex]
= [tex]8640 \ L[/tex]
As we know,
The ideal gad law equation will be:
⇒ [tex]PV = nRT[/tex]
⇒ [tex](\frac{47}{760} )\times 8640= n\times 0.082\times 310[/tex]
⇒ [tex]n=21\times 18[/tex]
⇒ [tex]n=378 \ g[/tex]
