HOW many elements are in this molecular FeCl3?
2
How many iron atoms are there in 5.33 moles of fecl3?
The formula shows that there is one atoms of iron in each formula unit of FeCl3, and by definition the number of molecules or formula units in a mole is Avogadro's Number. Therefore, 5.33 moles contains 5.33 X Avogadro's Number of atoms, which is 3.21 X 1024 atoms, to the justified number of significant digits.

How many electrons does the iron have when it forms the ionic compound FeCl3?
23 electrons
What substance is present in FeCl3 that gives a purple color?
Quite many compounds. Phenols are one of the most common group of compounds here. In other words: any compounds containing benzene ring connected to OH group will give you purple color when treated with FeCl3. It seems that if you have FeCL3 sample it is probably impurified by phenolic compounds.

How many milliliters of 0.200 M FeCl3 are needed to react with an excess of Na2S to produce 2.75 g of Fe2S3 if the percent yield for the reaction is 65.0 percent?
.2M x V FeCl3=moles FeCl3 x 1mole Fe2S3/2mole FeCl3=moles of Fe2S3 x mm of Fe2S3/1 mole Fe2S3= g Fe2S3 x .65% yield. 2.75g Fe2S3/ .65= 4.23g Fe2S3/ 207.91= .02035 x 2mole FeCl3=.0407 moles FeCl3/ .2M FeCl3= .2035 L x 1000= 203.5 ml

How many grams of FeCl3 does 5.88 X1028 weigh?
I don't have a good calculator, but i'll talk you through (will actually benefit you to do it yourself, this will come back to bite you if you don't learn it). Avagadros number is no. molecules per mole. 5.88x1028 / avagadros number gives your amount of moles. Moles / molecular weight gives weight
