<br />' Mass of MTBE = volume of processed water mass in micrograms per liter
<br /> MMTBE _ (2,512,702 liters)( 33 6 pg/1) = 84,426,787 pg MTBE
<br /> MMTBE =84,426,787 pg/1,000,000 = 84 4 g MTBE
<br /> MMTBE = 0 084kg MTBE (2 205 lb/kg) = 0 186 lbs of MTBE
<br /> A conversion factor of 2 205 Ib/kg can be used to convert MTBE to pounds
<br /> Mass of Benzene = volume of processed water mass in micrograms per liter
<br /> MBenzene = (2,512,702 liters)(? 13 pg/1) = 17,915,565 pg benzene
<br /> MBenzene = 17,915,565µg1 1,000,000 = 17 9 g benzene
<br /> MBenzene = 0 0179 kg oenzene (2 205 Ibikg) = 0 04 lbs of benzene
<br /> A conversion factor of 2 205 lb/kg can be used to convert benzene to pounds
