Question

If 0.155 moles of NaCl are dissolved in a 250.0 mL solution , what is the concentration of the NaCl solution?

Answer 1

Answer:

0.620mol/L

Explanation:

Concentration is described as number of moles/L of solution

Since we have 250mL of solution, we divide by 1000 to convert to L, which is 0.250L

We have the moles, great!!!

Now just divide

0.155/0.250 = 0.620mol/L

Hope that answers your question
