Answer:
4 moles of HCl are produced.
Step-by-step explanation:
Given data:
Mass of hydrogen = 4 g
Number of moles of HCl = ?
Solution:
H₂ + Cl₂ → 2HCl
Number of moles of hydrogen:
Number of moles = mass/molar mass
Number of moles = 4 g/2 g/mol
Number of moles = 2 mol
now we will compare the moles of hydrogen and HCl.
H₂ : HCl
1 : 2
2 : 2/1×2 = 4 mol
Thus, 4 moles of HCl are produced.
