Question

Uranium 238 undergoes radioactive decay through a series of stages, producing lead 206 (image attached). Dating analysis reveals that in a certain rock there is 0.228 mol of lead-206 for every mole of uranium-238. If all of the lead-206 is assumed to originate from uranium-238, the time since the formation of this rock is approximately :
