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, how much of the element would remain after 25 years

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 :

⇒

⇒

⇒

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

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
