radiometric dating formula

Radioactive dating. As time passes, carbon decays into nitrogen, releasing lots of energy! We can thus use these ratios of light isotopes to shed light on processes and temperatures of past events. Since Ar is a noble gas, it can escape from a magma or liquid easily, and it is thus assumed that no 40 Ar is present initially. The rate of creation of carbon appears to be roughly constant, as cross-checks of carbon dating with other dating methods show it gives consistent results. Problems If, when a hippopotamus lived, there was a total of 25 grams of Carbon, how many grams will remain years after he is laid to rest? The decay constant can be found with the equation.
