Nitrogen accounts for 78% of the atmosphere, oxygen 21% and argon 0.9%. Gases like carbon dioxide, nitrous oxides, methane, and ozone are trace gases that account for about a tenth of one percent of the atmosphere

b)75x2=150g
c)0.25x18=4.5
d)0.15x159.6=23.94g
Answer:
0.6 atm
Explanation:
We have a state change at a constant temperature. For isothermal transformations, Boyle proposed the equation:
P1V1 = P2V2 (Boyle's Law)
Where P1 and V1 are the pressure and the volume in the first state and P2 and V2 the pressure and the volume at the final state. So:
4x3 = 20xP2
20xP2 = 12
P2 = 0.6 atm
