How many liters of 15.0 molar naoh stock solution will be needed to make 20.0 liters of a 1.2 molar naoh solution? show the work used to solve this problem.

M₁V₁ = M₂V₂
15 * V₁ = 1.2 * 20 
V₁ = 1.6 L 

It is a mixture. simply put, a compound must be pure, that is, of only one chemical structure and composition. a mixture is made of different chemical substances (i.e. elements, molecules, compounds) that are not chemically bonded to each other, but instead physically grouped together, as in the case of gasoline (a homogeneous solution).
