Question

What is the molarity of an aqueous solution of sodium hydroxide produced when 35.0 ml of a 5.40 M solution was diluted to 890.0 ml?

Answer 1

Approx. `0.2*mol*L^-1`.

Explanation:

`"Concentration"` `=` `"Moles"/"Volume of solution"`.

And thus, `"Concentration"` `=` `(35.0xx10^-3Lxx5.40*mol*L^-1)/(890.0xx10^-3L)` `~=` `0.2*mol*L^-1`
