Answer:
Here's ya idea: Can the food we eat affect our heart rate?
Explanation:
24
Explanation:
we have the equation d = m/v so here the density is 12 and the volume is 2, 12 = m/2. in this situation we multiply 12×2= 24. The mass is 24.
Let's check if it works with the formula
24/2 = 12
12 = 24/2
yes. it works
the answer is mass = 24
The amount of the original isotope that remains after 30 days is 11.14.
<h3>What is the half life?</h3>
The half life of a radioactive nuclide has to do with the time that it takes for only half of the original number of nuclides to remain.
Now;
No = 150 grams
N = ?
t1/2 = 8 days
t = 30 days
Then;
N/No = (1/2)^t/t1/2
N/150 = (1/2)^30/8
N/150 = (1/2)^3.75
N = (1/2)^3.75 * 150
N = 11.14
