Mass spectrum of europium with percent intensity on the vertical axis and mass (amu) on the horizontal axis. The spectrum includes the percent intensities of two isotopes of europium, Eu-151 and Eu-153. To determine the atomic mass of europium. The peak representing Eu-151 has an exact mass of 150.91986 amu and percent intensity is assumed be to exactly 91.610%; the peak representing Eu-153 has an exact mass of 152.92138 amu and percent intensity of 100.00%. Express your answer to two decimal places with the appropriate units.
