What is the molarity of a solution containing 0.30 moles of FeCI3, dissolved in 150 ml of water

2M

Explanation:

Given parameters:

Number of moles of FeCl₃  = 0.3 moles

Volume of water  = 150mL

Unknown:

Molarity of solution = ?

Solution:

The molarity of a solution is the number of moles of solutes in a given solution. It is one of the ways of expressing concentration. The unit is always M i.e mol/dm³.

              Molarity  =

Express the volume in dm³;

                 150mL gives 0.15dm³

               Molarity  =

                                = 2M

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
