Answer:
option d = 3.125 g
Explanation:
Given data:
Mass of chemical = 100 g
Half life = 8 days
mass left after 40 days = ?
Solution:
First of all we will calculate the total half life's,
half life's = T (elapsed) / T half life
half life's = 40 / 8 = 5
starting mass = 100 g
half life's 1 2 3 4 5
Mass 100/2 50/2 25/2 12.5/2 6.25/2
50 g 25 g 12.5 g 6.25 g 3.125 g
