The amount of carbon-14 in the wood will be halved every 5700 years.
After the first half-life, which is 5700 years, the wood will have 10 grams of carbon-14.
After the second half-life, which is another 5700 years, the wood will have 5 grams of carbon-14.
After the third half-life, which is another 5700 years, the wood will have 2.5 grams of carbon-14.
Since we're rounding to the nearest gram, after 5700 years, the wood will have 2 grams of carbon-14.
Therefore, the answer is A. 2 grams.
The half life of carbon-14 is 5700 years. A certain sample of wood has 20 grams of carbon -14 when it is alive. How many grams of carbon will it have after 5700 years.
A. 2 grams.
B. 5 grams.
C. 10 grams.
D. 40 grams.
