Avogadro’s Law states that at a given temperature and pressure, what quantity is constant?
Answer:
Part A :
Avagadros law states that at a given temperature and presssure Volume of gas is proportional to number of moles
i.e V/n= constant
V= volume and n= number of moles
Part B:
each breath requires 0.060 moles of air. three breaths =0.060*3=0.18 moles
1.2 L correspoond to 0.18 moles of oxygen
3L corresponds to 3*0.18/1.2 =0.45 moles of oxygen
