At 20 deg C, 1 atm, and using the high estimate of 11.3kg, PV = nRT, which is

V

    n = 11300 g / 44 g/mol = 256.82 mol
    R = 8.314 L kPa K−1 mol−1
    T = 293 K
    P = 101.3 kPA

 = (256.82 * 8.314 * 293 / 101.3) L

 = 6175.8 liters

 = 3087.9 uncapped coke bottles every 15 minutes (high estimate)

At the low estimate:

n = 50 / 44 = 1.13 mol

So:

V = 27.33 L

  = 13.7 uncapped coke bottles every 15 minutes (low estimate)

Where did you get the mass estimates from?
