Answer:
There are 2,000 grams left after 300 years.
Step-by-step explanation:
Giving the following information:
The half-life of a radioactive substance is 200 years. There are 8000 grams of the substance initially.
<u>First, we need to calculate the reduction of the substance each year:</u>
Yearly reduction= 8,000/400= 20 grams per year
<u>Now, for 300 years:</u>
300 year reduction= 20*300= 6,000
There are 2,000 grams left after 300 years.
