Answer to Question #179658 in General Chemistry for Sophia Beer

Question

How many particles of H₂SO₄  are needed to react completely with 1.89 moles of H₂O ?

Answer 1

H₂0+SO₃ -> H₂SO₄

Mole ratio = 1:1

Therefore 1.89 moles of H₂O = 1.89 moles of H₂SO₄

1 mole = 6×10²³ particles

= 1.89 × 6× 10²³

= 1.134 × 10²⁴ particles
