    This is kinda AS stuff but my mind's gone completely blank :|

    How would you go about answering this question...

    "On complete reaction with water, 0.10g of potassium hydride yielded a solution requiring 25.0cm3 of 0.10 moldm-3 HCl for neutralisation. Calculate the relative atomic mass of potassium from this information"?

    Pleeaase and thank you (:

    Write a balanced equation for the reaction.

    Find the number of moles of HCL using (MxV)/1000

    Use the ratio of moles to find the number of moles of potassium hydride.

    Find the Mr using Mr = mass/moles
