Question

What volume (mL) of a concentrated solution of sodium hydroxide (6.00 M) must be diluted to 200.0 mL to make a 0.880 M solution of sodum hydroxide?

Answer 1

Approx. `30.0*mL`

Explanation:

We require a `200.0*mL` volume of `0.880*mol*L^-1` `NaOH(aq)`.

`"Moles of NaOH"=200.0xx10^(-3)Lxx0.880*mol*L^-1=0.1760*mol`.

We have `6.00*mol*L^-1` `NaOH` available, and thus `(0.1760*mol)/(6.00*mol*L^-1)` `=` `0.0293*L` of the original solution must be diluted to a `200.0*mL` volume.
