If a sample of gas occupies a volume of 6.80 L at 325°C, what will its volume be at 25.0°C if the pressure does not change?

3.4L

Explanation:

Given parameters:

Initial Volume of gas = 6.8L

Initial temperature of gas  = 325°C = 325 + 273  = 598K

Final temperature  = 25°C = 25 + 273  = 298K

Unknown:

Final volume  = ?

Solution:

To solve this problem, we apply the Charles's law. It can be expressed as;

              =

V and T are volume and temperature

1 and 2 are initial and final states

Now insert the parameters and solve;

              =  

          2026.4 = 598V2

          V2 = 3.4L

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).

the answer is d.) potassium
