A ballon weighing 50 kg is filled with 685.2 kg of helium at 1 atm pre – InterviewSolution

1.	A ballon weighing 50 kg is filled with 685.2 kg of helium at 1 atm pressure and 25^(@)C. What will be its pay load if it displaced 5108 kg of air ?
Answer» 4372.8 KG 4422.8 kg 5793.2 kg 5843.2 kg Solution :MASS of the filled balloon `=50+685.2` `=735.2`kg PAY LOAD = Mass of displaced air - Mass of balloon `=5108-735.2=4372.8 G` Hence, (A) is the correct answer.
