Answer:

The pressure of the gas is 26 atm.

Explanation:

This looks like the time to apply the Ideal Gas Law:

#color(blue)(|bar(ul(PV = nRT)|)#,

where

  • #P# is the pressure
  • #V# is the volume
  • #n# is the number of moles
  • #R# is the gas constant
  • #T# is the temperature

We can rearrange the Ideal Gas Law to get

#P = (nRT)/V#

#n = "4.95 mol"#
#R = "0.082 06 L·atm·K"^"-1""mol^"-1"#
#T = "(75 + 273.15) K = 348.15 K"#
#V = "5.4 L"#

#P = (nRT)/V = (4.95 color(red)(cancel(color(black)("mol"))) × "0.082 06" color(red)(cancel(color(black)("L")))"·atm·"color(red)(cancel(color(black)("K"^"-1""mol"^"-1"))) × 348.15 color(red)(cancel(color(black)("K"))))/(5.4 color(red)(cancel(color(black)("L")))) = "26 atm"#
