Question

For the following reaction, identify the number of moles of SO₂ and CrO₄^2– required to form 1 mole of Cr₂(SO₄)₃. Enter your answers as integers.

2CrO4 2−+ 3SO2 +4H+ > Cr2(SO4)3 +2H2O

Moles of SO2:

Moles of CrO4 2-:

Answer 1

2CrO₄²⁻+ 3SO₂ + 4H⁺ --> Cr₂(SO₄)₃ + 2H₂O ... balanced equation

mols SO2 to form 1 mole of Cr₂(SO₄)₃ = 3

mols CrO₄²⁻ to form 1 mole of Cr₂(SO₄)₃ = 2
