You set up a reaction with Gallium metal in excess hydrochloric acid at 28 degrees Celsius. It reacts in the following:

2Ga(s)+6HCl(aq)→2GaCl3(aq)+3H2(g)

You collect 171 mLs and 0.996 atm of hydrogen over water. How many moles of Ga reacted?

The partial pressure of water at 28 degrees is 0.0372 atm.

Remember sig figs

Expert Solution
Step 1

Given:

T = 28 deg C

P = 0.996 atm

PH2O = 0.0372 atm

V = 171 mL

Chemical Equaltion:

2Ga(s)+6HCl(aq)→2GaCl3(aq)+3H2(g)
