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.

1.25 g/L.

0.0214 mol/L.

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.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

girl imma just put my comment here because i need a couple point okurrttt
