Sloan [31]

Answer:

2.7724 g

Explanation:

Mass of pre- 1892 pennies = 3.1 g

Abundance = 45.4 %

Mass of post 1892 pennies = 2.5 g

Abundance = 100 - 45.4 = 54.6 %

The average mass is given as = ( 3.1 g * 45.4 / 100) + (2.5g * 54.6 / 100)

Average Mass = 3.1 * 0.454 + 2.5 * 0.546

Average Mass = 1.4074 + 1.365 = 2.7724 g
