Reaction of copper(II) carbonate with sulfuric acid: Moles of H2SO4 required Volume of H,So, required 5.3m Observations: liaht blue inihally bubbling Sue 61

Answer 1

Density of H₂SO₄=1.84g/mL

Mass of 5.3 mL H₂SO₄ =5.3×1.84=9.752 g

Molar mass of H₂SO₄=98.079 g/mol

Moles of H₂SO₄=9.752/98.079=0.099 moles
