# Is the density of solute same as the density of solution? [closed]

This problem came up while solving some problems on mass percentage and mole concept.

Essentially, our teacher said that the $$w/w\%$$ and the $$v/v\%$$ for a given solution will be the same, because in order to obtain $$v/v\%$$ there will be a mutual division by density.

However, the density of solute is different from density of solution, right? For example, the problem we were solving involved $$\ce{NaOH}$$ dissolved in water. But $$\ce{NaOH}$$ as a compound has a characteristic density, different from the density of the solution. So $$w/w$$ and $$v/v$$ should have different values, right?

I'm not sure if I'm able to clarify what I'm thinking, but I need help with this nonetheless.

• Maybe your teacher meant %w/v, otherwise no, it doesn't make sense. – Buck Thorn Aug 8 at 18:32
