    12.6 gram of HF will produced 0.315 moles of SnF₂

    Explanation:

    Given dа ta:

    Mass of HF = 12.6 g

    Moles of Tin fluoride produced = ?

    Solution:

    Chemical equation:

    Sn + 2HF → SnF₂ + H₂

    Number of moles of HF:

    Number of moles = mass / molar mass

    Number of moles = 12.6 g/20.01 g/mol

    Number of moles = 0.63 mol

    Now we will compare the moles of HF with SnF₂.

    HF : SnF₂

    2 : 1

    0.63 : 1/2*0.63 = 0.315 mol

    So 12.6 gram of HF will produced 0.315 moles of SnF₂.
