6. __________________________________________ is the measure of how much water vapor is in the air.

Answer:

V = 0.167L

Explanation:

We can use the ideal gas law:

PV = nRT

where P, V, and T are pressure, volume, and temperature (Kelvin only).  R is the gas constant and n is the moles of gas.

We want the volume of gas when the moles changes.  Let's set up two equations, 1 for each state.  Since both temperature and pressure are constant, we can simply use the terms P and T both states.

 Initial (0.553 moles and 253 ml)):  P*(0.253L) = (0.553 moles)RT

Second (0.365 moles, unknown volume, V):  P*V = (0.365 moles)RT

P*(0.253L) = (0.553 moles)RT

P*V = (0.365 moles)RT

  Lets set these up as a ratio:

      P*(0.253L)/P*V = ((0.553 moles)RT)/((0.365 moles)RT)

P, T and R all cancel to 1, and the moles unit cancels:

    (0.253L)/V = (0.553)/((0.365)

The ratio of the volumes is in direct proportion with the ratio of the moles.

Rearrange and solve:

        (0.253L) = (0.553)/((0.365)V

        (0.253L)*(0.365/0.553) = V

            V = 0.167L

Answer: Environment and the ecology.

Explanation:

The environmental science studies various aspects of environment involving the living and non- living components and their interaction. The ecology is the branch of environmental science which deals with the study of ecology in which involves the interaction of living beings with their non-living physical environment and with each other.

I think the answer is A.
