If you obtained a sample of Martian rock, determined the abundances of 230_U and 207_Pb in it, and found that for every one uranium atom there were seven lead atoms, then what would the age of this rock be? Note that 230_U decays to 207_Pb with a half-life of 700 million years. Assume that there was no 207_Pb in the rock when it originally formed.
