Question

What is the concentration with respect to sodium hydroxide if a `10*g` mass of same is dissolved in a `1*L` volume of solution?

Answer 1

`0.25*mol*L^-1`?

Explanation:

Take `10*g` sodium hydroxide, and dissolve this to a litre volume.

`"Concentration"` `=` `((10.0*g)/(40.00*g*mol^-1))/(1.00*L)` `=` `0.25*mol*L^-1` as required.

Because sodium hydroxide is hard to weigh out, your measurement may be a bit of problematic.
