Afossil was analyzed and determined to have a carbon-14 level that is 70 % that of living organisms. the half-life of c-14 is 5730 years. how old is the fossil? express your answer with the appropriate units. view available hint(s) t t t = nothing nothing

2948

Explanation:

Half life is the amount of time taken by a radioactive material to decay to half of its original value.

Expression for rate law for first order kinetics is given by:

where,

k = rate constant  =

t = age of sample  = ?

a = let initial amount of the reactant  = 100

a - x = amount left after decay process =

Thus the fossil is 2948 years old.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)
