What is the age of a sample if there are 6 grams of an element that have not decayed out an original 24 grams and has a half-life of 8yrs. a. 8yrs b. 50yrs c. 29yrs d. 16yrs

16 years is the age of a sample.

Explanation:

The equation used to calculate half life for first order kinetics:

where,  

k = rate constant 

= half life of the sample

t = time taken for decay process

= initial amount of the sample

[A] = amount left after decay process 

We are given:

= 24 grams

[A] = 6 grams

Putting values in above equation, we get:

Rate law expression for first order kinetics is given by the equation:

On substituting the values we get value of t:

t = 16.00 years

16 years is the age of a sample.

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
