Im confuse on whats the question is asking. differentiate between the subscript(s) and coefficient(s) that make up the chemical formula for sulfuric acid, $\ce{2H2SO4}$.

    $\begingroup$ Do you know in general, what subscripts and coefficients in a chemical formula are? Do you have problems with both terms or only one of them (which one?)? $\endgroup$ – Arsak Sep 25 '18 at 15:05
  • $\begingroup$ @mykhal I don't it matters much for someone who clearly doesn't know formula for sulphuric acid... $\endgroup$ – Mithoron Sep 25 '18 at 15:45

Subscripts and Coefficients both show the quantity of elements. The difference is that subscripts show the number of atoms in a molecule, while coefficients show the number of molecules there are. Also, subscripts are placed immediately after the atom it describes: $\ce{H2O}$. the 2 is describing the number of H atoms there are. $\ce{3H2O}$ is 3 molecules of $\ce{H2O}$.
