Question

In order to calculate the concentration in molarity of a salt solution, you need to know

A.
the mass of the salt added, the molar mass of the salt, the volume of water added, and the total volume of the solution.
B.
the mass of the salt added to the solution and the volume of water added to the solution
C.
the molar mass of the salt and the total volume of the solution
D.
the mass of the salt added, the molar mass of the salt, and the total volume of the solution

Answer 1

Answer:

The molarity of a solution is the concentration of moles of solute per liter of solution, mol/L . The mass of NaCl must be converted to grams and then moles. ...

1 g=1000 mg.

Divide the mass of NaCl by its molar mass by multiplying by its inverse.

1 L=1000 mL.
