    Let's assume that CO₂ has ideal gas behavior.

    Then we can use ideal gas formula to solve this.

    PV = nRT

    Where,

    P = Pressure of the gas (Pa)

    V = Volume of the gas (m³)

    n = moles of the gas (mol)

    R = Universal gas constant (8.314 J K⁻¹ mol⁻¹)

    T = Temperature in Kelvin (K)

    In this problem,

    P = Standard pressure = 1 atm = 101325 Pa

    V = 43 L = 43 x 10 ⁻³ m³

    R = 8.314 J K⁻¹ mol⁻¹

    T = standard temperature = 273 K

    n = ?

    PV = nRT

    By rearranging,

    n = PV / RT

    n = (101325 Pa x 43 x 10⁻³ m³) / (8.314 J K⁻¹ mol⁻¹ x 273 K)

    n = 1.92 mol

    Hence moles of CO₂ gas in 43 L at STP = 1.92 mol
