The following arrangement of flasks is set up$.$ Assuming no temperature change, determine the final pressure inside the system after all stopcocks are opened. The connecting tube

has zero volume.

$A=,Kr(g),V=3\mathrm{.}65L,P=0\mathrm{.}754$atm

$B=Ar(g),V=2\mathrm{.}81L,P=1\mathrm{.}29$atm

$C=O_2(g),V=5\mathrm{.}56L,P=2\mathrm{.}94$atm

Final pressure $=,$ atm
