Describe how would you prepare the following solution from pure solute

1.	Describe how would you prepare the following solution from pure solute and solvent (a) 1 L of aqueous solution of 1. 5 M Co Cl _(2). (b) 500 mL of 6.0 % (v //v) aqueous methanol solution.
Answer» Solution :(a) mass of `1.5` moles of `CoCl _(2) = 1. 5 xx 129.9 = 194 . 85g` (B) `194.85` g anhydrous cobalt CHLORIDE is dissolved in WATER and the solution is make up to one
