Question

The initial amount of carbon-14 is 100 g and the amount of carbon-14 d after decay process. The half-life of carbon-14 is 5.730 y. Calculate the complete this decay process.​

Answer 1

Explanation:

Explanation:

The half-life of carbon-14 is

5730

years.

Therefore, after

1

half-life there is

50

%

=

1

2

of the original amount left.

2

half-lives there is

25

%

=

1

4

of the original amount left.

3

half-lives there is

12.5

%

=

1

8

of the original amount left.

1

−

7

8

=

1

8

So, your answer would be the time it takes for carbon-14 to elapse 3 half-lives.

5730

⋅

3

=

17190
