Calculate how many liters of H2 gas at STP are produced from 2.11 moles of aluminum metal.

47.3 L of Hydrogen gas is produced from 2.11 moles of Aluminum metal.

Explanation:

We have to find the volume of hydrogen produced by writing the balanced equation as,

2Al(s) + 6HCl(aq) → 2AlCl₃(aq) + 3H₂(g)

We can use the ideal gas equation at STP,

Temperature = 273.15K

Pressure = 1 atm

Gas constant being 0.08205 L atm K⁻¹ mol⁻¹

Number of moles = 2.11 moles

PV = nRT

Plugin the values as,

      = 47.3 L

So 47.3 L of Hydrogen gas is produced from 2.11 moles of Aluminum metal.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
