Very hot zinc will react with steam to form zinc oxide and hydrogen. What volume of steam would be necessary in order to use up 20.0 g of zinc completely? What volume of hydrogen would be produced in this case?
I NEED HELP WITH THIS!!..PLEASE = )

• Chem -

1.Write the equation.
2. Convert 20.0g Zn to mols Zn.
3. Using the equation convert mols Zn to mols H2O (steam).
4. Convert mols H2O (steam) to volume using mols x 22.4 L/mol = ?? L.

The part on hydrogen is a separate question but is worked by the same principles.
