Answer:
111.6 g
Explanation:
Given
m + M = 2.58 / 9.8
= 0.2632 kg
When the can of fruit juice is balance from scale , we get following relation
M x ( 50 - 21.2 ) = m x 21.2 ( balancing the torque due to weight of scale and can about the balancing point )
M x 28.8 = 21.2 m
= 21.2 ( 0.2632 - M )
= 5.58 - 21.2 M
M ( 28.8 + 21.2 ) = 5.58
M = .1116 kg
= 111.6 g
