Answer:
B = 6.06 g
Step-by-step explanation:
Chemical equation:
2Al + 6HCl → 2AlCl₃ + 3H₂
In given balance chemical equation there are 3 moles of hydrogen are formed.
Mass of hydrogen in gram:
Formula:
Number of moles = mass/molar mass
Mass = number of moles × molar mass
Molar mass of hydrogen = 1.008×2 = 2.016 g/mol
Mass = 2.016 g/mol× 3 mol
Mass = 6.05 g
It is almost equal to 6.06 g thus option B is correct.
