Question

A chemist prepares a solution of iron(II) chlorlde (FeCl,) by measuring out 0.45 g of FeCl, into a 50. mL volumetric flask and filling to the mark with distilled water. Calculate the molarity of CI anions in the chemist's solution. Be sure your answer is rounded to the correct number of significant digits. mol L ? X Check Explanation 9 o 8-940ud You The

Answer 1

Fech iron (II) chloride Molar mass = m= (56+2x 35.5)) gm mol = 127 g/mol W= 0.45 gr. nou of moles (n) = 0.45 gm. 127 gmimol - 0.00354 moles. volume of solution=50ml = 0.050 lt. molarity of cd im = 2x0.00354 moles 0:050 (nei= an) 10.142 Mol . Ito
