Step-by-step explanation:

the element would remain after 25 years is 2,325 grams !

Step-by-step explanation:

Here we have , Element X is a radioactive isotope such that every 13 years, its mass decreases by half. Given that the initial mass of a sample of Element X is 8800 grams, We need to find how much of the element would remain after 25 years . Let's find out:

According to question , Element X is a radioactive isotope such that every 13 years, its mass decreases by half , And initial mass of a sample of Element X is 8800 grams . So , following equation will be framed for the mass of sample X after t years as :

⇒

⇒

Now , the mass of element after 25 years is given by :

⇒

⇒

⇒ m=2.325

Therefore , the element would remain after 25 years is 2,325 grams !
