What is the molarity of a solution that contains 125 g NaCl in 4.00 L solution?

a.8. 56 M

b.31.3 M

c. 2.14 M

d/ 0.535 M

    For these molarity problems, just remember the definition.
    Molarity = # mols/Liter of solution.
    So convert grams NaCl to moles (# moles = g/molar mass) and divide by the number of liters. Voila!

    I assume the molmass of NaCl is about 58

    Molarity=mass/(molmass*literssolution)

  • chemistry help -

    is it b

  • chemistry help -

    NO. do the calculation. You wouldn't want to get the reputation of being an answer moocher.

  • chemistry help -

    i did it and i got d

  • chemistry help -

    good, excellent
