Determine the molecular formula of iron (III) chloride and establish the molarity equation and determine the concentration of Cl- in 10 g iron (III) chloride in 0.1 L of solution
The rules for naming binary ionic compoundsare as follows:
1. The metal keeps its name and is named and written first.
– For transition metals, we use Roman numerals to denote its charge.
What is the concentration of chloride ions when 10.0 grams of iron(III) chloride (formula mass = 162.2 g/mol) is dissolved in water to form 0.100 L of solution?
(A) 0.616 M
(B) 1.23 M
(C) 0.1 M
(D) 6.16 × 10−4 M
(E) 1.85 M
