A chemist prepares a solution of zinc nitrate ($Zn(NO_3)_2$) by measuring out $1.8 \times 10^2$ µmol of zinc nitrate into a 250. mL volumetric flask and filling the flask to the mark with water. Calculate the concentration in µmol/L of the chemist's zinc nitrate solution. Round your answer to 2 significant digits.
