    4 Rb + O₂ → 2 Rb₂O

    Number of moles Rb = 82.4 g / 85.47 g/mol = 0.964

    Number of moles O ₂ = 11.6 g / 32 g/mol = 0.363

    the ratio between Rb and O ₂ is 4 : 1 so Rb is the limiting reactant

    Moles Rb ₂ O = 0.964 / 2 = 0.482

    Mass Rb ₂ O = 0.482 mol x 186.94 g/mol = 90.1 g

    % yield = 39.7 x 100 / 90.1 = 44.1
