    P₂ = 175.5 atm

    Explanation:

    Given dа ta:

    Initial pressure of gas = 85.0 atm

    Initial temperature = 19°C (19 + 273 = 292 K)

    Final temperature = 330°C (330 + 273 = 603 K)

    Final pressure = ?

    Solution:

    P₁/T₁ = P₂/T₂

    Initial pressure = P₁

    Initial temperature = T₁

    Final pressure = P₂

    Final temperature = T₂

    P₁/T₁ = P₂/T₂

    P₂ = P₁T₂/T₁

    P₂ = 85.0 atm. 603 K) / 292 K

    P₂ = 51255 atm. K / 292 K

    P₂ = 175.5 atm
