Question

What mass of Kr?91 (atomic mass 90.92 amu) is produced by the complete fission of 12g  of U?235 (atomic mass 235.04 amu)?          Express your answer using two significant figures.

Consider the fission reaction: 23592U+10n?14256Ba+9136Kr+310n+Energy
23592U+10n?14256Ba+9136Kr+310n+Energy
