The sum of the partial pressures is equal to the total pressure.

Explanation:

$Dalton's Law of partial pressures$ $"Dalton's Law of partial pressures"$ holds that in a gaseous mixture, the total pressure is the sum of the individual partial pressures; i.e. the sum of the pressures of the components if they ALONE occupied the container.

You have a real dog's breakfast of pressure terms here that can only have come from the US of A.

Anyway the total pressure is...................

$P_{Total} = 2558 \cdot psi = \frac{2558 \cdot psi}{14.7 \cdot psi \cdot a t m^{- 1}} = 174 \cdot a t m = 174 \cdot bar................................$ $P_"Total"=2558*"psi"=(2558*"psi")/(14.7*"psi"*atm^-1)=174*atm=174*"bar................................"$

which is a prodigiously high pressure. (Note that $1 \cdot bar$ $1*"bar"$ is as near as dammit equal to $1 \cdot a t m$ $1*atm$ ).

Now $P_{Total} = P_{N O_{2}} + P_{C O_{2}}$ $P_"Total"=P_(NO_2)+P_(CO_2)$

And thus..................................

$P_{N O_{2}} = P_{Total} - P_{C O_{2}} = (174 - 54.6) \cdot a t m = 119.4 \cdot a t m$ $P_(NO_2)=P_"Total"-P_(CO_2)=(174-54.6)*atm=119.4*atm$ .

These are exceptionally high pressures, and the vessel containing these gases would be exceptionally sturdy.
