0.269 mol

Explanation:

To get the corresponding number of moles from the given grams of the compound, simply divide the moles by its molecular mass.

In this example,

$m o l R b_{2} S = 54.6 g R b_{2} S \cdot (\frac{1 m o l}{203.00 g R b_{2} S})$ $mol Rb_2S = 54.6 g Rb_2S * ([1 mol]/[203.00g Rb_2S])$
$m o l R b_{2} S = 0.269$ $mol Rb_2S = 0.269$
