The volume of a certain gas is 29.3 liters at STP. What would be the volume of the same gas at 1.39 atmospheres and -23.00C? (R=0.0821 L-atm/mol. k)
19.3L
22.4L
23.0L
37.31

19.32L

Explanation:

Given parameters:

Volume of the gas at STP = 29.3liters;

      Using this information first, let us find the number of moles of the gas.

                  Number of moles =

With the number of moles, we can further solve this problem;

                 Number of moles  =   = 1.31 moles

More parameters;

Pressure on gas  = 1.39atm

temperature  = -23°C  = -23 + 273  = 250K

Unknown:

Volume of gas  = ?

Solution:

The ideal gas equation is the perfect fix to solve this problem.

It is mathematically expressed as;

              Pv  = nRT

where P is the pressure

           v is the volume

           R is the gas constant

            n is the number of moles

            T is the temperature

     Input the parameters;

             1.39 x V  = 1.31 x 0.082 x 250

                     V  = 19.32L

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.

you have the answer? i really need it
