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 mass of the solute is:

For the room, we know:

The volume of the room is:

The resulting concentration in ppmv is:

they are made of gases.

they have a spherical shape.

they make energy through fusion.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
