cooper and nickel can be mixed to form a corrosion resistant alloy. if a particular alloy is prepared by mixing 13.7 moles of cooper with 1.00 moles of nickel. what is the mass percentage of nickel in the alloy
Homework Answers
Answer :
Molar mass of Cu = 63.5 g /mol
1mol of Cu has mass = 63.5 g
13.7 mole of Cu has mass = 13.7 * 63.5 = 869.95 g
Molar mass of Ni = 58.69 g/mol
1 mol of Ni has mass = 58.69 g
Total mass of alloy = mass of 13.7 moles of Cu + mass of 1 mol of Ni = 869.95 + 58.69 = 928.64 g
% of Ni in the alloy = (mass of Ni / total mass of alloy) * 100 = (58.69 / 928.64 ) * 100 = 6.32 %

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...
