What is the molarity of a solution that is made with 3 moles of Na and 2 L of water

Answer - 1.50 M Na

Explanation -

3.00 moles of Na over 2.00 L of water.

3.00/2.00 = 1.50 M Na

I cannot be entirely sure. But it's an educated guess.

Molarity

=

Moles of solute

Volume of SOLUTION

.

And we get an answer with units,  

m o l ⋅ L − 1

Explanation:

So all we need to do is to set up this quotient. You have been given the amount of solute in moles, and the volume of solution.

So,  

Molarity = 3 ⋅ m o l 4 ⋅ L = ? ? mo l ⋅ L − 1 ? In  1 L

of this solution, what is the mass of the  

N a C l  solute?

Explanation:

it should be all of them because it asks if you included all of those in your answer
