**DrBob222**, Tuesday, February 21, 2012 at 4:11pmdensity = g/mL = 36,000/200,000 = 0.18. It floats.

We can add mass until the density is 1.00 g/mL.

1.0 = mass/volume

V*1.0 = mass = 200,000 1 = 200,000 g

The barge has a mass of 36,000; therefore, 200,000-36,000 = 164,000g = mass to be added. Check to see density = 1.0 g/L. d = m/v = 200,000/200,000 = 1.0 g/mL.
