So,
Remembet that the equation to find molarity is given by:
We're asked to find the volume of the solution, which means the liters of solution. To do this, we need to find the moles of solute first. Our solute is NaCl and we have 43.9 grams of it. To find the moles, we divide these grams by the molar mass of NaCl, which is 58.44g/mol.
Now that we have the moles, we use the first equation:
The volume of the solution in liters, is 0.54L.
