    The question is incomplete, the complete question is;

    . A chemist determined by measurements that 0.015 moles of hydrogen chloride participate in a chemical reaction. Calculate the mass of hydrogen chloride that participates Round your answer to 2 significant digits. x S. ?

    Answer:

    0.54 g

    Explanation:

    Recall that;

    Number of moles = mass/molar mass

    Molar mass of HCl =36.5 g/mol

    Mass= number of moles × molar mass

    Mass= 0.015 moles × 36 g/mol

    Mass= 0.54 g
