(2x32g) + (3x32g) ⇒ (2 x 80g)
64 g + 96 g ⇒ 160g
1.Calcular masa de azufre (REGLA DE TRES)
100% ⇒ 250 g S
98% ⇒ X
x = 98% x 250 g S
100%
X = 245 g de S
2.CALCULAR MASA DEL SO₃
64 g S ----- 160 g SO₃
245 g S ------ X
x = 245 g S x 160 g SO₃
64 g S
X = 612.5 g SO₃
3. ECUACION DE FORMACION DEL ÁCIDO SULFURICO:
SO₃ + H₂O ⇒ H₂SO₄
80 g + 18 g ⇒ 98 g
4.CALCULAR MASA DEL ACIDO SULFURICO
80 g SO₃ --------98 g H₂SO₄
612.5 g SO₃ ------ x
x = 612,5 g SO₃ x 98 g H₂SO₄
80 g SO₃
x = 750.31 g de H₂SO₄
