# Problem: 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.Calculate the initial molarity of MCHM in the river, assuming that the first part of the river is 7.10 feet deep, 100.0 yards wide, and 100.0 yards long. 1 gallon = 3.785 L.
