An aqueous solution of NH4Cl weighs 5 kg. The solution has 2 moles of NH4Cl present in it. The Density of the solution is 1.25 g/ml. (Atomic masses of N=14 ,H=1, Cl=35.5) Find the

a) Molarity of the solution

b) Molality of the solution.

c) Number of molecules of NH4Cl in the solution.

d) Number of H atoms in the solution.

e) If the solution is diluted to double its volume, what will be the Molarity of the solution?

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).
