Mass of Hydrogen gas produced : 3.202 g
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Hydrogen gas can be obtained by reacting metals with acids
Reaction of Aluminium(Al) and Hydrochloric acid(HCl)
2Al + 6HCl → 2AlCl₃ + 3H₂
mass of Aluminium : 28.56 g, so mol Al :
[tex]\tt \dfrac{28.56}{26.98}=1.059~moles[/tex]
From equation, mol ratio of Al : H₂ = 2 : 3, so mol H₂ :
[tex]\tt \dfrac{3}{2}\times 1.059=1.5885[/tex]
Mass of Hydrogen gas produced :
[tex]\tt mass=mol\times MW\\\\mass=1.5885\times 2.016\\\\mass=3.202~g[/tex]
