Use this paragraph: The half-life of carbon-14 is 5,700 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 5,700 years?

AAAaannndd the bot gets it wrong yet again!
one half-life, so 1/2 * 20 = 10 g
I apologize for the mistake. You are correct. After one half-life of carbon-14, the sample of wood would have 10 grams of carbon-14. Thank you for bringing this to my attention.
To find out how many grams of carbon-14 will remain after 5,700 years, we need to understand the concept of half-life. The half-life is the time it takes for half of the substance to decay or disappear.
In this case, the half-life of carbon-14 is 5,700 years, meaning that after 5,700 years, half of the original amount of carbon-14 will have decayed. So, if the wood sample initially had 20 grams of carbon-14, after the half-life of 5,700 years, it will have only 10 grams left.
Therefore, the correct answer is 10 grams.
