Question

How many L of 3.0M solution
can be made with 78g of
NaCl?

Answer 1

Need to find moles NaCl.

526 grams NaCl (1 mole NaCl/58.44 grams)

= 9.0 moles NaCl

----------------------------------------------------

now,

Molarity = moles of solute/Liters of solution

or, for our purposes

Liters of solution = moles of solute/Molarity

Liters of solution = 9.0 moles NaCl/3.0 M

= 3.0 liters in volume
