Question

How many moles of solute particles are present in 1 mL (exact) of aqueous 0.0060 M `Ba(OH)_2`?

Answer 1

`3xx1xx10^-3cancelLxx 6.0xx10^-3*mol*cancel(L^-1)` `=` `18xx10^-6* mol`

Explanation:

Barium hydroxide is an electrolyte that gives `Ba^(2+)` and `2 " equiv "HO^-` ions upon dissolution.

`"Volume "(L)xx"concentration "(mol*L^-1)` `=` `"moles, amount of subtance."`
