INTERACTIVE EXAMPLE Using Dalton's Law of Partial Pressures II
Hydrogen gas is produced by the reaction of hydrochloric acid, HCl, on zinc metal.
2HCl(aq) + Zn(s) → ZnCl₂(aq) + H₂(g)
The gas is collected over water. If 152 mL of gas is collected at 19°C and 768 torr total pressure, what is the mass of hydrogen collected? The vapor pressure of water
at 19°C is 16.5 torr.
HOW DO WE GET THERE?
You have the following data for the gas.
Value
0.989 atm
0.152 L
