Suppose there is a mineral body which contained some amount of superscript 238 baseline upper u, which has a half-life of 4.51 times 10 superscript 9 years, but has no lead, the end product of the radioactive decay of superscript 238 baseline upper u. if the ratio of superscript 238 baseline upper u to lead atoms today is 0.42, how long ago did the mineral body form?

A gas behaves more like an ideal gas at higher temperature and lower pressure, as the potential energy due to intermolecular forces.
