1. If 22.5 L of nitrogen at 1.25 atm are compressed to 2.10 atm at constant temperature. What is the new
volume?

V₂ = 13.4 L

Explanation:

Given data:

Initial volume of gas = 22.5 L

Initial pressure = 1.25 atm

Final pressure = 2.10 atm

Final volume = ?

Solution:

The given problem will be solved through the Boly's law,

"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"

Mathematical expression:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = initial volume

P₂ = final pressure

V₂ = final volume  

Now we will put the values in formula,

P₁V₁ = P₂V₂

1.25 atm × 22.5 L = 2.10 atm × V₂

V₂ = 28.125 atm. L/ 2.10 atm

V₂ = 13.4 L

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).
