How long will it take for 10. grams of carbon-14 to decay to 2.5 grams? (carbon-14 half life = 5730 years.)

## How long does it take for carbon-14 to undergo 2 half lives?

5730 years The half-life of carbon-14 is 5730 years. 1 half-life there is 50%=12 of the original amount left. 2 half-lives there is 25%=14 of the original amount left. 3 half-lives there is 12.5%=18 of the original amount left.

## How many years does it take for 100 g of carbon-14 to decay?

But after 5000 years, however, almost half of the carbon-14 has decayed .Decay of carbon-14.t (years)m (ng to 4 decimal places)0100.000010098.7973100088.6034200078.50563 more rows

## What is the lifespan of carbon-14?

5,730 ± 40 years Carbon-14 has a half-life of 5,730 ± 40 years—i.e., half the amount of the radioisotope present at any given time will undergo spontaneous disintegration during the succeeding 5,730 years.

## Why does carbon-14 take so long to decay?

The reason involves the strong three-nucleon forces (a nucleon is either a neutron or a proton) within each carbon-14 nucleus. Its all about the simultaneous interactions among any three nucleons and the resulting influence on the decay of carbon-14.
