Aflask contains a gas mixture of methane, hydrogen, and nitrogen with partial pressures of 1 atm, 1.2 atm, and 1.1 atm, respectively. what is the total pressure of the mixture?

3.3 atm

Explanation:

This is a simple application of Dalton's law of partial pressure which state that the total pressure exerted by a mixture of gas is the sum of the individual partial pressure of the component gases.

Hence, the total pressure of the gas mixture becomes:

                         = 1 + 1.2 + 1.1

                                 = 3.3 atm

The total pressure of the mixture is 3.3 atm

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).
