Question

Oblicz ile g. NaOH potrzeba do zobojetnienia 49g H 2małeSO 4małe

Answer 1

M(NaOH)=40g/mol
M(H2SO4)=98g/mol

2NaOH + H2SO4= 2H2O + Na2SO4

2*40g/mol(NaOH) ------98g/mol(H2SO4)
xg(NaOH) ------49g(H2SO4)
x=40gNaOH

Answer 2

M(NaOH)=40g/mol
M(H2SO4)=98g/mol

2NaOH + H₂SO₄= 2H₂O + Na₂SO₄

2*40g/mol(NaOH) 98g/mol(H₂SO₄)
xg(NaOH) - 49g(H₂SO₄)
x=40gNaOH
