Aclumsy chemist drops a beaker containing 404 ml of a solvent (mw = 88.2, sg = 1.37) in a room measuring 21 ft x 10 ft x 10 ft. assuming that the contents of the beaker completely evaporate and fill the space, what is the resulting concentration in parts per million by volume (ppmv)? assume normal temperature and pressure (ntp), i.e., p = 1 atm, and t = 25 celsius. 1 ft3 = 28.3 l

9.4 ppmv

Explanation:

Parts per million by volume means milligrams of solute per liter of solution. Then, we have to find the mass of the solvent in mg (which in this context is the solute) and the volume of the room in L (which in this context is the volume of the solution).

For the solute, we know:

The volume is 404 mL.The specific gravity is 1.37, which means that the density is 1.37 g/mL.1 g = 1000 mg.

The mass of the solute is:

For the room, we know:

The dimensions are 21 ft × 10 ft × 10 ft.1 ft³ = 28.3 L

The volume of the room is:

The resulting concentration in ppmv is:

C. his outrage over the deployment of us troops in saudi arabia
us troops have never deployed in saudi arabia which happens to be one of  america's  biggest ally
(on a side note al qaeda was set up by the us during the cold war to oppose ussr and was not  set up  after wards to promote terrorism, it's all just propaganda.)
