O CHEMICAL REACTIONS Calculating molarity using solute moles A chemist prepares a solution of mercury(II) iodide (HgI₂) by measuring out 0.0161 μmol of mercury(II) iodide into a 300. mL volumetric flask and filling the flask to the mark with water. Calculate the concentration in μmol/L of the chemist's mercury(II) iodide solution. Round your answer to 3 significant digits. µ mol L Explanation Check x10 X Ś Q Search 2023 McGraw Hill LLC.
