Answer: The rock is 2000785 years old.
Explanation:
Expression for rate law for first order kinetics is given by:
where,
k = rate constant
t = age of sample
a = initial amount of the reactant = 800
x = amount of daughter isotope = 600
a - x = amount left after decay process = amount of parent isotope = (800-600) = 200
Half life is the amount of time taken by a radioactive material to decay to half of its original value.

It is least likely that Japan will be experiencing population growth.
Explanation:
Japan is a country that has a very large population for a country of its size, over 120 million people. Japan though, faces huge demographic problems, which will be more and more serious as the years pass by. The problems now are not that the population is very large, but that the population is aging and will start to experience sharp decrease in the coming decades.
The total fertility rate (TFR) of the country is only 1.27, which is far from enough for simple replacement of the population, as for that a TFR of 2 is needed. Less and less children are born, which in turn provides smaller and smaller population for reproduction with each generation. On the other hand, Japan is a country that has one of the highest life expectancy in the world, and the old population is constantly on the rise.
Such situation brings in lot of economic problems, as very soon the number of old people will equal the number of people of working age, and that is almost impossible to be managed. The Japanese governments have been trying to persuade the young people to form a family and have more children, but the reality is the opposite, as more and more young people decide to be solitary, not form a family, and if they do, they tend to have one child, or maybe two.
