A chemist prepares a solution of nickel(II) chloride (NiCl,) by measuring out 11. umol of nickel(II) chloride into a 150. mL volumetric flask and filling the flask to the mark with water. Calculate the concentration in umol/L of the chemist's nickel(II) chloride solution. Be sure your answer has the correct number of significant digits. u mol
