    1.29 atm.

    Explanation:

    To calculate the volume of a gas, we can use the general law of ideal gas: PV = nRT.

    where, P is the pressure of the gas in atm.

    V is the volume of the gas in L.

    n is the no. of moles of the gas in mol.

    R is the general gas constant,

    T is the temperature of the gas in K.

    If n and T are constant, and have two different values of V and P:

    P₁V₁ = P₂V₂

    P1 = 2.15 atm, V1 = 750 mL = 0.75 L.

    P₂ = ? atm, V₂ = 1.25 L.

    ∴ P₂ = P₁V₁/V₂ = (2.15 atm) (0.75 L) / (1.25 L) = 1.29 atm.
