Answer:
First, let's add up the masses:
M&Mium: 15.45g
Skittlitium: 12.96g
MPeanuttium: 10.00g
Now, we can find the sum:
15.45g + 12.96g + 10.00g = 38.41g
To find the average, divide the sum by the number of elements (3 in this case):
38.41g ÷ 3 = 12.80g
Therefore, the average mass for each element is approximately 12.80g.
