What is the molarity of a solution that contains 125 g NaCl in 4.00 L solution?
a.8. 56 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
is it b
NO. do the calculation. You wouldn't want to get the reputation of being an answer moocher.
i did it and i got d
