Total mass = 4 gram

Mass left after 90 days = ?

Solution:

Number of half lives passed:

Number of half lives = Time elapsed / half life

Number of half lives = 90 days / 30 days

Number of half lives = 3

At time zero = 4 g

At first half life = 4g/2 = 2 g

At 2nd half life = 2g/ 2= 1 g

At 3rd half life = 1 g/2 = 0.5 g
