Answer:
76.1N
Explanation:
Given parameters: 
Mass of the ball  = 7.77kg 
Unknow: 
Weight of balloon  = ? 
Solution: 
Weight is the vertical force applied on a body. 
   Weight = mass x acceleration due gravity 
So; 
   Weight  = mass x acceleration due to gravity 
 So; 
  Weight  = 7.77 x 9.8  = 76.1N
