58. A cylinder of a gas mixture used for calibration of blood gas analyzers in medical laboratories contains 5.0% CO2, 12.0% O2, and the remainder N2 at a total pressure of 146 atm. What is the partial pressure of each component of this gas? (The percentages given indicate the percent of the total pressure that is due to each component.)

Answer and Explanation:

[tex]Greetings![/tex]

[tex]Let's~answer~your~question![/tex]

[tex]Partial ~pressure ~of ~gas ~can ~be ~directly~ calculated ~by ~multiplying ~the~ percentage\\ of~ pressure~ of~ gases~ to ~the ~total ~pressure.[/tex]

[tex]\boxed{Pgas~ = ~P~total~ * \% ~P ~of ~gas}[/tex]

For % of N2 gas:

[tex]100\% - (5\% + 12\%) = 83\% ~N2[/tex]

[tex]PN_2 ~= ~146~ atm~ *~ 0.83 ~ = 121.18 ~atm[/tex]

[tex]PO_2 ~= ~146~ atm~ *~ 0.12~ = 17.52 ~atm[/tex]

[tex]~PCO_2~ = ~146~ atm ~* 0.05 = 7.3 ~atm[/tex]
