3.132 g of Zinc reacts with excess HCl to produce H2 gas and ZnCl2 at atmospheric pressure of 752 mmHg and a temperature of 21.0 oC. If the partial pressure of water vapor is 18.65 mmHg at 21.0 oC.
How many liters of H2 gas can be collected over water?
Step-by-Step
1. Write the balanced chemical equation.
2. Organize the data given.
3. Find what data is needed to calculate the volume (of hydrogen gas) from the idea gas law equation.
4. Calculate the moles of hydrogen gas.
5. Calculate the pressure of hydrogen gas.
6. Determine the volume of hydrogen gas using the ideal gas law equation.
