    P = 2.18 atm

    Explanation:

    The strategy here here is to use the ideal gas law

    PV = nRT

    since we know the temperature, volume and the n, the number of moles is mass/MW, and R is the gas constant 0.08205 LatmK⁻¹mol⁻¹:

    MW HI = 127.91 gmol⁻¹

    P = (mass / MW) x R x T / V

    P = (50.0 g / 127.91 gmol⁻¹) x 0.08205 LatmK⁻¹mol⁻¹ x 340 K / 5.00 L

    P = 2.18 atm

    (rounded to three significant figures which is the number of significant figures for temperature, mass and volume)
