Three samples of gas each exert a pressure of 740 mmHg. What is the total pressure? a. 247 mmHg b. 740 mmHg c. 1480 mmHg d. 2220 mmHg

Option D 2220mmHg

Because there are three samples each with pressure as 740mmHg so in order to find the total pressure we multiply it by 3

I hope this will help you :)

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).
