Question

A chemist prepares a solution of mercury(1) chloride (Hg,C1, by measuring out 0.44 mg of mercury(1) chloride into a 300 ml volumetric flask and filling the Flask to the mark with water. Calculate the concentration in mol/L of the chemist's mercury(I) chloride solution, Round your answer to 2 significant digits.

Answer 1

molauty (M) solute per liter number at moles at at Solution. molarity - moles at solute Liters at solution (mol) mole - given mass (ingen) molarmuss molar mass ab given mass = Hg₂ Cl2 = 472.09 g/mol 0.nung = 0.000 44g. mole = 0.000 ung 472.0ggmori = 9,320 X 107 mol 300 me = 0.3 L molwrity = 9.320 x 10-7 mol 0.3 L - 3.10 x 10-6 mol So concentration at Hg2 Cl2 is [ 3.10 X 100 ml
