When 4.48 grams of silver metal are dropped in 1000. mL of 2.0 M acetic acid, how many liters of gas r evolved

Answer 1

I believe the net ionic equation will be:

Ag(s) + 2 H+(aq) --> H2(g) + 2 Ag+(aq)

So, you'll get one mole of gas for every mole of Ag(s)

In order to calculate this, divide the mass of silver by the atomic mass of silver. This will give you the moles of silver in 4.48 grams, and will also be the moles of hydrogen gas formed.

There are a couple of ways to get to the volume of gas. One way is to multiply the moles of hydrogen by 22.4 L/mol. Alternatively, you could use the ideal gas law to calculate an exact volume of gas at a specific temperature and pressure.
