Answer:
Mass = 134.4 g
Explanation:
Given data:
Mass of hydrochloric acid = 100 g
Mass of sulfuric acid produced = ?
Solution:
Chemical equation:
2HCl + K₂SO₄ → H₂SO₄ + 2KCl
Number of moles of HCl:
Number of moles = mass / molar mass
Number of moles = 100 g/ 36.5 g/mol
Number of moles = 2.74 mol
Now we will compare the moles of HCl with H₂SO₄
HCl : H₂SO₄
2 : 1
2.74 : 1/2×2.74 = 1.37 mol
Mass of H₂SO₄:
Mass = number of moles × molar mass
Mass = 1.37 mol × 98.1 g/mol
Mass = 134.4 g
