Answer:
52.7 g
Step-by-step explanation:
We are given;
- Initial mass of the element is 310 g
- Rate of decay 8.9% per minute
- Time for the decay 19 minutes
We are required to determine the amount of the element that will remain after 19 minutes.
We can use the formula;
New mass = Original mass × (1-r)^n
Where n is the time taken and r is the rate of decay.
Therefore;
Remaining mass = 310 g × (1-0.089)^19
= 52.748 g
= 52.7 g (to the nearest 10th)
Thus, the mass that will remain after 9 minutes will be 52.7 g
