Answer:
6.21 times more
Step-by-step explanation:
Assuming 2.04 x 10^11 was only a typo
you would need to first equal the powers of 10
so 20.4 x 10^10 and 3.28 x 10^10
now that they have the same powers
if it's asking for how many times i would approximate it to 6.21 times more
Answer : The substances half life in days is, 5.6 days.
Step-by-step explanation :
Half life : It is defined as the amount of time taken by a radioactive material to decay to half of its original value.
All radioactive decays follow first order kinetics.
The relation between the half-life and rate constant is:
where,
k = rate constant = 0.1235 per days
= half-life
Now put all the given values in the above formula, we get:
Thus, the substances half life in days is, 5.6 days.
