How many moles of chloride ions are in 0.2550 g of aluminum chloride using alcl3 's molar mass of 133.34 g / mol: ?

Explanation:

It is known that number of moles is the amount of mass present in a given molar mass of the substance.

Mathematically,   No. of moles =

We are given that mass of is 0.255 g and molar mass of is 133.34 g/mol.

Therefore, number of moles of is calculated as follows.

        No. of moles =

                              =  

                              = mol

Since, there are three chlorine atoms present in one mole of . Therefore, moles of chlorine ions present in given 0.255 g will be calculated as follows.

              mol

            =

Thus, we can conclude that chloride ions are in 0.2550 g of aluminum chloride using 's molar mass of 133.34 g/mol.
