How do i convert from mol dm-3 ( e.g. 0.768) to g dm-3, I am confused which Mr to use.
The equation is the following:
H2SO4 (aq) + 2NH3 (aq) → (NH4)2SO4 (aq)

Just convert the mol value into grams by using mol = mass/ formula mass

So mol x Mr of whatever molecule yuu have the concentration value for should do the trick

If you have 0.3moldm^-3 of something for example, then the gdm^-3 is just the moles times the relative atomic number (if it's an element) or the relative molecular mass (if it's a compound or molecule).

Moles = mass/RAM or RMM
Therefore mass = Moles * RAM or RMM
