How much water should be added to 0.07 moles of KCL to prepare a 0.5m solution

                       Volume  =  0.14 L

Explanation:

                     This is a simple Molarity problem in which we are given with,

Moles  =  0.07 moles

Molarity  =  0.5 mol.L⁻¹

Volume  =  ??

Now, as,

            Molarity is the amount of solute dissolved per unit volume of solution. It is expressed as,

                         Molarity  =  Moles / Volume of Solution   

So, Solving for Volume,

                         Volume  =  Moles / Molarity

Now, putting value of Moles and Molarity,

                        Volume  =  0.07 mol ÷ 0.5 mol.L⁻¹

                        Volume  =  0.14 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).
