You are starting with a stock solution containing 90.00 mg/mL Nickel(II) chloride (NCl2; molar mass = 129.599g/mol).
1. Convert the mg/mL concentration into molarity (moles/L).
2. To make your standard solutions, dilute the following volumes of stock solution to a total volume of 25.00mL and convert the concentrations to millimolar (mM).
