Answer:
2.29 L
Explanation:
In this question we have to start with the chemical reaction:
The reaction is already balanced. So, if we have an excess of HCl the compound that would limit the production of would be Zn. So, we have to follow a few steps:
1) Convert from grams to moles (Using the atomic mass of Zn 65.38 g/mol).
2) Convert from moles of Zn to moles of (Using the molar mass 1 mol = 1 mol Zn).
3) Convert from mol of to volume (Using the ideal gas equation PV=nRT).
We have to remember that R = 0.082
Moles of zn
- 55.8/65
- 0.86mol
1 mol produces 1 mol H2
- Moles of H_2=n=0.86mol
- P=1.07atm
- T=299K
So
Ideal gas equation
- PV=nRT
- V=nRT/P
- V=0.86(8.314)(299)/1.07
- V=1.998L
