Question

The half-life of carbon-14 is approximately 6000 years. How much of 800 g

Answer 1

Answer:

25 g will be left after 30,000

Explanation:

First how many time it decays in 30,000 years: 30,000 ÷ 6000

The answer will be 5 times, it decays.

Now use the formula:

$\frac{m}{2^n}$ ............where m is mass and n is number of times it decays.

Here given mass is 800 g and decays 5 times

Using the formula:

$\frac{800}{2^5}$

25 g

Answer 2

Answer:

300 i think im not sure also carbon full life lives 10000 years good to know right
