What is the chemical formula (with charge) of the phosphate ion ? A white powder

Question

What is the chemical formula (with charge) of the phosphate ion ? A white powder is 50.2% chloride ion by mass. Use dimensional analysis to determine how many grams of this powder will contain 2.561 grams of chloride. The news over the last decade has talked about whether or not Iran is enriching uranium. This process is essentially separating Uranium-238 from the more abundant Uranium-235 isotope. What do the numbers in Uranium-235 and Uranium-238 mean and what do they tell you about the essential difference between these isotopes?

Explanation / Answer

1)PO43-

2)The weight of powder which contains 2.561 g of chloride=(2.561x100)/50.2=5.101g

3) uranium-238 means mass number=238,atomic number =92

uranium-235 means mass number=235,atomic number=92

that is the number of nuetrons are different
