A lot of that hydrochloric acrid is excess and some grams will not react, I think. Balanced equation first.
Zn + 2HCl -> ZnCl2 + H2
Check to make sure of limiting reactant; I suspect zinc.
1.80 moles Zn (2 mole HCl/1 mole Zn) = 3.60 moles HCl
You have a lot more than that, Zn limits and will drive the reaction
1.80 moles Zn (2 moles HCl/1 mole Zn)(36.458 grams/1 mole HCl)
= 131 grams of hydrochloric acid reacted with that Zinc amount

How many points in one liter?
If you need (for example) three parts water and one part hydrochloric acid, that just means you need a 3:1 ratio of water to hydrochloric acid. It could mean three liters of water and one liter of hydrochloric acid, three mL of water and one mL of hydrochloric acid, three cups of water and one cup of hydrochloric acid, etc.
How many moles of formic acid is there in 25 grams of acetic acid?
I think you meant " How many moles of acetic acid in 25 grams of acetic acid? " We will use the chemist formula for acetic acid, 25 grams C2H4O2 (1 mole C2H4O2/60.052 grams) = 0.42 mole acetic acid =================

Non!!!! They are two different substances/acids. The formulas for sulphuric acid is H2SO4 and for hydrochloric acid (HCl). With the exception of the hydrogens all the other elements present in the two difference acids are different.
