Sodium Chloride (NaCl) has a molecular mass of 58 grams/mole. What is the molarity of a NaCl solution with a
Vera_Pavlovna [14]

Answer:

2nd option

Explanation:

Molarity is the number of moles of the solute (NaCl) in 1 litre of the solution (NaCl solution).

Given: concentration= 232g/ L

what we are trying to achieve is __mol/ L.

So in 1 litre, we have 232g of NaCl.

To convert mass to mole, we divide it by the Mr.

Given that the Mr is 58g/mol,

number of moles

= 232 ÷58

= 4

Thus, 1 litre has 4 moles of NaCl.

Therefore, the molarity is 4.0 mol/L.
