How do u do this???
What amount of solute ions, in moles, is present in 50cm3 of 0.10moldm3 sodium hydroxide solution?

ok m8 dead easy....
In simple the question is asking you to calculate the number of moles present in 50cm³ of 0.10dm³ solution of sodium Hydorxide
so you must be familiar with the pyramid Moles = conc x vol (dm³)
therfore moles = 0.1 x (50)/(1000)
= 0.005 Moles
