Question: 1. Triple-quad GC/MS was recently used to analyze a sample of water from the Ohio River for 2,2',4,4'- Tetrabromodiphenyl ether (2,2',4,4' TBDE), a toxic component

1. Triple-quad GC/MS was recently used to analyze a sample of water from the Ohio River for 2,2',4,4'- Tetrabromodiphenyl ether (2,2',4,4' TBDE), a toxic component with very, very low water solubility. Analysis gave a signal area of 103.5 for one sample 2,2,4,4 TBDE. A spike of 5.00L of 3.00mM2,2,4,4 TBDE was added to 95.00L this solution. The final spiked solution gave a 2,2',4,4' TBDE signal area of 259.0. Determine the concentration of 2,2,4,4 TBDE in the original water sample in ppmw/v. (2,2,4,4 TBDE formula mass =485.79g/mol) (SHOW ALL CALCULATIONS and UNITS)
