When aluminum is placed in concentrated hydrochloric acid, hydrogen gas is produced. 2 al ( s ) + 6 hcl ( aq ) ⟶ 2 alcl 3 ( aq ) + 3 h 2 ( g ) what volume of h 2 ( g ) is produced when 3.60 g al ( s ) reacts at stp?

The volume of hydrogen gas produced at STP is 4.90 liters.

Explanation:

Moles of aluminium =

According to reaction , 2 moles of aluminium gives 3 moles of hydrogen gas.

Then 0.1333 moles of aluminium will give:

of hydrogen gas

Volume of 0.2 moles of hydrogen gas at STP = V

Temperature at STP = T = 298.15 K

Pressure at STP = P = 1 atm

n = 0.2 mol

PV = nRT (Ideal gas equation)

The volume of hydrogen gas produced at STP is 4.90 liters.
