A chemist makes 0.410L of mercury (II) iodide (HgI2) working solution by adding solution by adding distilled water to 0.0900L of a 0.0000350 M stock solution of mercury (II) iodide in water. Calculate the concentration of the chemists working solution.

Ans. : frostbite is when exposure to cold temperatures causes freezing to the skin or other tissues. it most commonly affects the hands, feet, and face. the longer areas are exposed to cold, typically the worse the frostbite. the water temperature used for rewarming a frostbitten part should be : (102 -105) f degrees.
