1) Rubidium has two naturally occurring isotopes, rubidium-85 (atomic mass = 84.9118
amu; abundance = 72.15 %) and rubidium-87 (atomic mass = 86.9092 amu; abundance =
27.85 %). Calculate the atomic weight of rubidium.

When the net torque acting on a system is equal to zero, it is in rotational
equilibrium. This lab established the rotational equilibrium by using multiple
scenarios. This was accomplished by using a meter stick and various coins. The
