Do you know the concentration of the solution? i.e. Molarity?

anonymous · Answer

no thats my entire question :/

joannablackwelder · Answer

Hmm, are you sure? It says the sodium chloride solution, as if it was referred to previously...

anonymous · Answer

NaCl - 0.1 Mole 
is that it i didnt read any one certain solution in the lesson it just gives me this

joannablackwelder · Answer

The question is asking for moles. I wouldn't think they would give it to you and then not give you that answer choice. Is it written NaCl - 0.1 M?

joannablackwelder · Answer

With a capital M?
