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.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
