Question

what is stoichiometric coefficient in a balanced chemical equation?

Open in App

Solution

Stoichiometric coefficient are the number of moles of each reactant and product in the balanced chemical equation.
For ex.,
6 FeSO₄ + K₂Cr₂O₇ + 7 H₂SO₄ = 3 Fe₂(SO₄)₃ + Cr₂(SO₄)₃ + K₂SO₄ + 7 H₂O
The stoichiometric coefficient are 6,1,7,3,1,1,7
