A 1500mL balloon is at 475 torr and the pressure increase to 900 torr. What is the new volume?

P1 = 475 torr

P2 = 900 torr

V1 = 1500 mL

V2 = ?

Applying Boyle's Law

P1V1 = P2V2

475 torr × 1500 mL = 900 torr × V2

V2 = 475 * 1500 mL / 900

V2 = 475*5/3 = 791.6 mL

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).
