Part (b) We're being asked to calculate the mass, in grams, of 0.0255 mol of iron(III) phosphate.
We first need to determine the chemical formula of iron(III) phosphate:
The rules for naming polyatomic ionic compounds are as follows:
1. The metal keeps its name and is named and written first.
– For transition metals, we use Roman numerals to denote their charge.
2. Name the polyatomic ion as you would normally.
(b) What is the mass, in grams, of 0.0255 mol of iron(III) phosphate? g
