Question

Assume you add 5 g of Nacl to a beaker and add water until the volume of the solution reaches 4 L. Calculate the concentration of salt in water in g/L and mol/L.

Answer 1

1.25 g/L.

0.0214 mol/L.

Step-by-step explanation:

Concentration in g/L = 5/4

= 1.25 g/L (answer).

As for mol / L we need to know the molar mass of salt.

It is 22.99 + 35.45 = 58.44.

So in mol/L it is 1.25 / 58.44

= 0.0214 mol/L.
