I have 50 grams of an isotope. How much of it will i have in 10 years if it has a half life of 10 years
If the half-life is 10 years, and you have 50 grams now, you will have half that, or 25 gms., in 10 years. That's what half-life means. ☺☺☺☺
Explain what happens to the frequency of sound as it draws closer. What will you hear
To calculate how much of the isotope you will have in 10 years, you need to use the concept of half-life.
The half-life is the amount of time it takes for half of the original sample of the isotope to decay. In this case, if the half-life of your isotope is 10 years, it means that after 10 years, half of the initial amount will have decayed and half will remain.
To calculate the amount remaining after 10 years, you can follow these steps:
1. Determine the number of half-lives that have passed in 10 years. Since the half-life of your isotope is 10 years, the number of half-lives that have passed is equal to the total time (10 years) divided by the half-life (10 years). In this case, 10/10 = 1 half-life.
2. Calculate the fraction of the isotope remaining after 1 half-life. Since half of the original sample decays in each half-life, after 1 half-life, you will have 1/2 of the original amount remaining.
3. Multiply the fraction remaining after 1 half-life by the original amount of the isotope to find out how much you will have after 10 years. In this case, you have 50 grams of the isotope, so multiplying 1/2 by 50 grams gives you 25 grams.
Therefore, after 10 years, you will have 25 grams of the isotope remaining.
