This is a portion of a solved solution.
In 2014, a major chemical leak at a facility in West Virginia released 7500 gallons of MCHM (4-methylcyclohexylmethanol, C8H16O) into the Elk River. The density of MCHM is 0.9074 g/mL.
How much farther down the river would the spill have to spread in order to achieve a "safe" MCHM concentration of 1.00 10-4 M? Assume the depth and width of the river are constant and the concentration of MCHM is uniform along the length of the spill.
