Question

= STOICHIOMETRY Calculating molarity using solute moles calculating A chemist prepares a solution of mercury(IT) iodide (Hgl) by measuring out 0.00253 umol of mercury(II) iodide into a 300 mL volumetric flask and filling the flask to the mark with water. Calculate the concentration in moll of the chemist's mercury(II) iodide solution. Round your answer to 3 significant digits. 2

Answer 1

Mola nity Ob a solshion' Ms numbed Ob moles volume of the solution (in 2) = number ob moles x 1000 volume of the solution in me .Mola nity Ob menery CIJ) Iodide 0.00253x10° x 1000 300 = 0.0253x106 molesih :. concentration ob the solution = 00253x10 molesih = 0.00843 tio mulesil 63 8.43x109 molesih
