In $1993$ the Minnesota Department of Health set a health risk limit for BCME in groundwater of $2\mathrm{.}00n\frac{g}{L}.$

Suppose an analytical chemist receives a sample of groundwater with a measured volume of $85\mathrm{.}0mL.$ Calculate the maximum mass in milligrams of BCME which the chemist could measure in this sample and still certify that the groundwater from which it came met Minnesota Department of Health standards.
