Answer:
Formula we will be using:
(i) ,
where
Final quantity
Initial quantity
t=time ( same unit as that of half-life)
n=half-life
-------------------------------------------------------------
Given,
Final quantity ==0.100g
Initial quantity==0.750g
Time= t(unknown)
Half-life=n=3.823 days
Plug in the above values in the formula:
Divide both sides by 0.750:
Taking natural long on both sides:
Applying
Dividing both sides by ln(0.5):
Multiplying both sides by 3.823:
11.113=t
t=11.113
It would take 11.113 days
Answer : 11.113 days
