Answer:
The amount remaining after 24 hours is 17.5 milligrams.
Step-by-step explanation:
The rate of decay is proportional to the amount of the substance present at a time
The equation is
Rate=k*amount remaining at(time)
Where k = constant of proportionality.
So we don't know the value of k, let's find it.
7= k(70)(6)
K= 1/60
Amount remaining after 24 hours
7= 1/60 * x* (24)
(60*7)/24= x
17.5 = x
The amount remaining after 24 hours is 17.5 milligrams.
