The wrappings from a mummy discovered in an Egyptian tomb in the Valley of Kings was dated by counting its 14C content. 14C decays by a first-order process with a half-life of 5730 years.
A) What is the rate constant, k, for the decay of carbon-14? Show your work, including units and the equation you used.
B) The mummy wrappings were found to have 75% of the 14C activity/gram that one would expect to find in a modern artifact. What is the approximate age of the mummy?
Somewhat less than 2,500 years
Somewhat more than 2,500 years
About 4,300 years
About 5,700 year

A mummified cat is found in an ancient Egyptian tomb. The activity per gram of carbon is found to be 10 decay/(min g). The mass of carbon-12 is 12 u (by definition), where u = 1.66 X 10-27 kg. If the half-life of Carbon-14 is 5730 years, then how old is the cat?

Suppose an Egyptian mummy is discovered in which the amount of carbon-14 present is only about - the amount found in living human beings. The amount of carbon-14 present in animal bones after t years is given by y, where is the amount of carbon-14 present in living human beings. About how long ago did the Egyptian die?

Radiocarbon dating of a sample of wood from the tomb of an Egyptian pharaoh found that in the 1 gram of the sample there were 9.843 times 10^-15 mol of C-14 and 1.202 times 10^-2 mol of C-12. The C-14 isotope is radioactive and decays with a half-life of 5, 730 years: the C-12 isotope is stable (does not decay). If the initial ratio of these isotopes is known to have been Number of C-14/Number of C-12 = 1.20 times...
