Strange wording. I assume you want to know % yield when 20g Znb produced 5.4L H2.
Zn + H2O ==> ZnO + H2
mols Zn = grams/atomic mass
Use the coefficients in the balanced equation to convert mols Zn to mols H2. Note that is a 1:1 conversion.
Then convert mols Zn to L.
1 mol occupies 22.4L. This is the theoretical yield The actual yield 5.4 L.
%yield = (actual yield/theor yeild)*100 = ?
very hot sinc will react with steam to form zinc oxide and hydrogen. If 5.4 liters of hydrogen was used to use up 20 g of zinc completely. What is the percent yield of this process
