Question

You breathe in 12.0 l of pure oxygen at 298 k and 1,000 kpa to fill your lungs. how many moles of oxygen did you take in? use the ideal gas law: pv = nrt where r=8.31 l*kpa/mol*k

Answer 1

Below

Step-by-step explanation:

PV = n RT given re-arrange to

PV/(RT) = n plug in the given values (since all of the units 'match-up '

1000 * 12.0 / ( 8.31 * 298) = n = 4.85 moles
