    Answer:

    Explanation:

    1 psi = 6894.76 Pa

    P = 184 psi = 12.686 x 10⁵ Pa .

    Temperature T = 95⁰F = 35⁰C= 308 K

    volume V = 18 ft³ = 18 x 0.0283168 m³

    = .51 m³

    From the gas law

    PV/RT = n where n is mole of gas

    = 12.686 x 10⁵ x  .51  / 8.31 x 308

    = 252.78 gm mole

    = 252.78 x 32 gm

    = 8.08896 kg

    = 2.20462 x 8.08896 lb

    = 17.833 lb

    = 17.833 / 32 lbf

    = .5573 lbf

    weight of tank = 150 lbf

    Total weight = 150 + .5573

    = 150.5573 lbf .
