Answer: The balanced chemical equation for the reaction is:
Mg + 2 HCl → MgCl2 + H2
The molar ratio between MgCl2 and Mg is 1:1, which means that for every 1 mole of Mg that reacts, 1 mole of MgCl2 is produced. Therefore, the number of moles of MgCl2 produced can be calculated by simply using the same number of moles of Mg that reacts.
Given that 2.55 mol of Mg is reacting, the number of moles of MgCl2 produced can be calculated as:
2.55 mol Mg × (1 mol MgCl2/1 mol Mg) = 2.55 mol MgCl2
Now, to convert moles of MgCl2 to grams, we need to multiply the number of moles by the molar mass of MgCl2, which is 95.21 g/mol.
2.55 mol MgCl2 × 95.21 g/mol = 242.89 g MgCl2
Therefore, 2.55 mol of Mg will produce 242.89 g of MgCl2.
