first step: what is your balanced equation?
then start using moles.
m(ZnO) - ?
m (HCl) - ?
w(HCl) = 5%
m(ZnCl) = 13,64 gram

this is the exercice he didn t give me the balanced equation but i think it s like that
ZnO + hcl --->zncl + ho
ZnO + hcl --->zncl + ho
Your effort has a good start, shows you have an idea what's needed, but,
to balance equations, you have to know what the possible products are.
For example, HO and ZnCl are not known products to me.
If you lookup/Google Zinc Chloride, and Hydrogen Oxide, you will find the proper name (together with a laugh) and chemical composition of each product.
Then the next step is to balance the equation, mathematically.
Please proceed, and post if you have difficulties.

it s really hard how can i find the equation ??please help me
ZnO + 2HCl ---> ZnCl2 + H2O
By the way H2O is ......
Zn = 65 g/mol
O = 16 g/mol
H = 1 g/mol
Cl =35.5 g/mol
13.64 g ZnCl2 * 1 mol/(65+71)g
= mols of ZnCl2
now you should be able to continue.
