    Answer:

    0.500 moles

    Explanation:

    In order to convert grams of any given substance into moles, we need the substance’s molar mass:

    • Molar Mass of CH₃Br = Molar Mass of C + (Molar Mass of H)*3 + Molar Mass of Br

    We can find the molar masses of each element in the periodic table:

    • Molar Mass of CH₃Br = 94.94 g/mol

    Now we can divide the given mass by the molar mass in order to calculate the number of moles:

    • 47.5 g ÷ 94.94 g/mol = 0.500 moles
