Natural uranium consists almost entirely of 238U. To operate a nuclear power reactor, the fuel must be enriched in a lighter fissionable isotope, 235U. If the average molar mass of uranium in a reactor is 236.98, what percent of the fuel consists of the lighter isotope? Assume that the masses of the two isotopes are exactly 235 and 238 amu
