H2SO4+KOH= g + f

Now what i need here is the atomweight .. or something like that (sry ime from europe) if i know that the weight of the H2SO4 is 0.5 mol.

So basicly i need the atomweight of each and every element

H2SO4 + 2KOH -> K2SO4 + 2H2O
please don't use the equal but the arrow, it's a reaction.

the molecular weights are easily calculable by summing the atomic weights of each element for each compound.
atomic weights (if you don't know them by heart) are easily found in the periodic table of the elements.

as explained above, moles are not a measure of weight, but you can calculate the weight of the compound from the moles once that you finished calculating the molecular weights (MW) using the formula
weight (grams) = MW * mol

so your reaction tells you:
0.5 mol of sulphuric acid react with 1mol (2 equivalent) of potassium hydroxide to give 0.5mol of potassium sulphate and 1mol of water

H2SO4 + 2 KOH -> K2SO4 + 2 H2O

Data required, your being from Europe doesn't change the question.

Moles are not units of weight. They are units of quantity. Just like a "dozen" means 12, a mole means 6.02*10^23.

Find the atomic mass of a mole of each atom, using the periodic table. For H, it's about 1g. For S, it's about 32. For O, it's about 16g.

If you have 0.5 moles of the compound H2SO4, then for each atom, you have 1 mole of H, 0.5 moles of S and 2 moles of O. Using the above atomic masses, thats 1g H, 16g S, and 32g O.

Since you did not specify the amount of KOH you have, you cannot calculate the weight of those atoms.
