If the concentration of sulfuric acid is 4.2 mol dm^3 , when asked to show in the form of g dm^3 , why is it not c*2 *98.1? There are 2 hydrogen atoms, so why do you not do 4.2*2*98.1?
Thanks
Thanks
They gave you the concentration of H2s04 so why would you multiply by 2. Your miss understanding why you would ever x2. If they ask for ph and h+ conc then you would use x2 in those calculations because it is diprotic. All your doing is converting units your not doing anything to the relative value of the concentration.
gdm3 / mr + moldm3 so moldm3 x mr = gdm3
