Electrospray time‑of‑flight (TOF) mass spectrometry was used to analyze the eluate from a high‑performance liquid chromatography (HPLC) separation. The mass spectrum of one chromatographic peak, containing a protein of unknown molecular mass, displays MHnn+ peaks at m/z= 6636.908, 6194.524, 5807.480, 5465.932, 5162.360, and 4890.726. Find the average molecular mass (M) of the neutral protein and its standard deviation.

Determine the minimum dissolved oxygen (DO) concentration in a river downstream from a wastewater treatment plant (WWTP) discharging at a flow rate of 5.00 million gallons per day (MGD). The WWTP achieves secondary treatment standards (BOD5 = 30 mg/L). The wastewater temperature is 25.0 °C and contains 4.0 mg/L of DO. The characteristics of the river upstream from the point of discharge are Q=20.0 cubic feet per second (cfs), T = 20.0°C, BODu = 3.0 mg/L. and DO = 7.0...
