Uranium-235 (u-235) radioactively decays into lead-207 (pb-207). i'm measuring the number of atoms in a mineral, and i find that there are 500 atoms of u-235 and 1500 atoms of pb-207. if we assume the mineral contained only parent and no daughter, then how many atoms of these elements were in the mineral when the rock first formed?

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.
