What is the molarity of a 2.0 L sodium hydroxide solution containing 10.0 grams of solute?

1 Answer

Sep 11, 2017

#"Molarity"=0.125*mol*L^-1#

Explanation:

We take the quotient, #((10.0*g)/(40.00*g*mol^-1))/(2.0*L)=0.125*mol*L^-1#.

Note the dimensional consistency of the answer....#1/(mol^-1)=1/(1/(mol))=mol#.

What are the concentrations with respect to #Na^+# and #HO^-# ions?

What is the pH of this solution?
