WebHint: The original 1 mg sample is a mix of 12 C and 14 C with atomic masses of 12 and 14 dalton (atomic mass units) respectively. Use that to find how many 14 C atoms were there initially, and then find the number remaining at this time from known decay rate. The number remaining will be more than 10 18, so divide your answer by 10 18 and give ... WebMost carbon atoms weigh 12 atomic mass units. However, roughly one in a trillion carbon atoms weighs 14 atomic units. This carbon is called carbon-14. It is also called radio carbon because it is radio active (but not dangerous). Half of it …
WebBut each molecule of water contains 2 H and 1 O atom = 3 atoms, so there are approximately 1.8 x 1024 atoms in a mole of water. ... How many atoms are in 1g of water? Thus, there are 3.35 * 10^22 molecules of water in 1 gram. Now, each molecule of water has 2 hydrogen atoms and 1 oxygen atom. This means that there are 3 atoms in each … WebThe term is most commonly used in relation to atoms undergoing radioactive decay, but can be used to describe other types of decay, whether exponential or not. One of the most well-known applications of half-life is carbon-14 dating. The half-life of carbon-14 is approximately 5,730 years, and it can be reliably used to measure dates up to ...
