Formula to get solution :- moles = grams / molar mass
1. Mass of NH4NO3 = 0.0500 mole × 80.043 grams /1mole
= 4.0022 grams
2 Mass of NH4NO3 = 0.0375 mole × 80.043gram / 1mole
= 3.002 grams
3. Mass of NH4NO3 = 0.0250 mole × 80.043 gram / 1mole
= 2.0011 grams
4. Each sample tested twice =4.0022× 2+3.002 ×2 + 2.0011× 2
= 8.0044 + 6.004 + 4.0022
total amount of salt = 18.1 grams

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
