    Answer:

    hydrochloric acid has a molar mass of

    36.46 g/mol

    , which means that the

    164-g

    sample will contain

    164

    g

    1 mole HCl

    36.46

    g

    =

    4.498 moles HCl

    As you know, molarity is defined as moles of solute, which in this case is hydrochloric acid, divided by liters of solution

    molarity

    =

    moles of solute

    liters of solution

    A

    6.0-M

    hydrochloric acid solution will contain

    6

    moles of hydrochloric acid for every liter of solution. This means that

    4.498

    moles will come with a volume of

    c

    =

    n

    V

    V

    =

    n

    c

    V

    =

    4.498

    moles

    6.0

    moles

    L

    =

    0.7497 L
