Answer:
Mass = 507.6 g
Explanation:
Given data:
Mass of Mg = 48 g
Mass of iodine react = ?
Solution:
Chemical equation:
Mg + I₂ → MgI₂
Now we will determine the number of moles of Mg.
Number of moles = mass/ molar mass
Number of moles = 48 g/ 24 g/mol
Number of moles = 2 mol
Now we will compare the moles of Mg with iodine.
Mg : I₂
1 : 1
2 : 2
Mass of iodine:
Mass = number of moles × molar mass
Mass = 2 mol × 253.8 g/mol
Mass = 507.6 g
