How old is the specimen if the half-life is 300 years and there is 15 times more daughter product than parent material?
Wiki User
∙ 14y ago
Age = no. of half lives x duration of each half life
ratio of Parent nuclei : Daughter Nuclei
1 : 15
total of 16 parts, and for every 16 parts one part is a parent nuclei
Mt = Mo x (0.5)^n
Mt = amount remaining
Mo = Initial amount
n = number of 1/2 lives
Mt = 1/16
(1/2)^n = 1/16
(1/2)^n = (1/2)^4
n=4
Age = 4 x duration of each half life
Age = 4 x 300
Age = 1200
Therefore, the age of the specimen is 1200 years.

A specimen is found to have 3 atoms of a radioactive isotope for every 9 atoms of the stable decay product The radioactive material has a half-life of 2500 years how old is the specimen?
5000 years old
When a material goes through radioactive decay there is a new daughter product in the solid material so can this new daughter material react chemically with the rest of the solid matrix around it?
Yes, this new daughter is a different chemical element and will react differently chemically than the precursor element.
What is the daughter product of Xenon?
The main daughter product is Caesium.
Is Direct Material a product cost?
Yes direct material is a product cost as without material no product can be manufactured.
How many half-lives have passed in a rock containing one eighth of the original radioactive material and seven eighths of the daughter product?
3 half-lives
Is direct material used a product cost?
Yes direct material is part of product cost and included in calculating the product price.
Is Direct Material a product cost or period cost?
Direct material is a product cost because without material no product can be produce and it has direct relation with production of goods.
After three half lives what fraction of the daughter product has formed?
91.16% of the daughter product has formed after 3.5 half lives.
Is carbon dioxide a product or reactant?
Carbon dioxide, in photosynthesis, is a reactant, or "raw material" and in cellular respiration, is a product or end product, so it is really either, but the answer to the question according to the category is a "raw material."
What is direct material and direct labor?
Direct material is material that is contained in the final product. Direct labor is labor that ultimately forms the final product.
