Answer:
Step-by-step explanation:
Let 
denote the half life of our substance 
to be our time, 
is mass at time t and 
as initial mass. Our half life equation can be expressed as:
from which we can obtained mass at any given time.
b. From our equation above,
we can convert our t into mins as 
We then substitute value into the equation
Hence mass after 4hrs is 
c. We can set our final mass to 
then substitute in the equation
. Substitute 
Hence time until mass is 109.83 minutes
Step-by-step explanation:
