37.5 mL of oxygen gas is collected at a pressure of 772 mm Hg. What is it’s volume at 716 mm Hg?

The volume of the gas at 716 mmHg comes out to be 40.43 mL. This problem is solved by using below equation.

 at constant temperature

Explanation:

Initial volume of gas = V = 37.5 mL

Initial pressure of gas = P = 772 mmHg

Final pressure of gas = P' = 716 mmHg

Assuming final volume of the gas to be V' mL.

   at constant temperature

Hence, volume of oxygen gas at 716 mmHg is 40.43 mL.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

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).
