Answer:
Mass of each weight = 56.7 gram per piece
Explanation:
Given:
Lead’s density = 11.34 g/mL
Number of weights = 50
Volume of box = 250 mL
Find:
Mass of each weight
Computation:
Mass = volume x density
Mass = 250 x 11.34
Mass = 2,835 gram
Mass of each weight = Total Mass / Number of weights
Mass of each weight = 2,835 / 50
Mass of each weight = 56.7 gram per piece
