Dissolving 6.25 mg of sugar in 100 ml water gives a solution with which concentration of sugar (in ppm)? 6.25 0.0625 62.5 625

Convert a healthy plasma concentration of human growth hormone (hGH) 5.5 ng/mL) to a percentage.

3. An important conversion factor that you must memorize and use in this course is: 1 mg/L = 8.34 lb/million gallons a) Start with a value of 1 mg/L and use dimensional analysis to prove that this conversion factor is correct: Show that 1 mg/L = 8.34 lb/million gal. b) A wastewater treatment plant adds 5 mg/L of a commercial polymer to raw water to enhance removal of colloidal particles during settling. If the flow rate of water into the facility is 100 MGD, how many pounds of polymer are needed each year? (hint, use the required conversion factor 1 mg/L = 8.34 lb/million gallon to perform the calculation)
