    1>Ok so first we have to know that Rubidium Sulfate is Rb2SO4 (just google it)

    2>? mol Rb2SO4 = 150g Rb2SO4

    3> (add up the atomic mass) Rb = 85.47 x2 = 107.94

    S = 32.06 x1 = 32.06

    O = 16.00 x4 = 64.00

    107.94+32.06+64.00=204g Rb2SO4

    4> divide: 150g Rb2SO4 / 204Rb2SO4 =.735 mol Rb2SO4
