Final answer:
5.0 kg of magnesium will form 2475 g of Epsom salts. Correct option is 2475g.
Step-by-step explanation:
The formula for Epsom salts is MgSO₄⋅7H₂O. To determine the number of grams of Epsom salts formed from 5.0 kg of magnesium, we need to consider the stoichiometry of the reaction. The equation for the formation of Epsom salts is:
2Mg + H₂SO₄ → MgSO₄ + H₂
From the balanced equation, we can see that 1 mole of magnesium reacts to form 1 mole of Epsom salts. The molar mass of Epsom salts is 120.4 g/mol. Therefore, the number of grams of Epsom salts formed can be calculated as:
5.0 kg x (1000 g/1 kg) x (1 mol/24.31 g) x (120.4 g/1 mol) = 2475 g
Therefore, the correct answer is 2475 g.
