Answer» Solution: M₁v₁ + M₂v₂ + M₃v₃ = Mv → 2(1 M × 200 ML) + 3 M × 300 mL + 2 M × 100 mL = M × 1000 L → 400 + 900 + 200 = 1000M → 1500 = 1000 M → 1.5 = M (OPTION 2) Focus ♦ We did 2(1 M × 200 mL) in case of H₂SO₄ because H₂SO₄ has basicity of 2 while HCl has basicity of 1. Hence answer is 1.5 MOLARITY

Answer»

Solution: M₁v₁ + M₂v₂ + M₃v₃ = Mv

→ 2(1 M × 200 ML) + 3 M × 300 mL + 2 M × 100 mL = M × 1000 L

→ 400 + 900 + 200 = 1000M

→ 1500 = 1000 M

→ 1.5 = M (OPTION 2)

♦ We did 2(1 M × 200 mL) in case of H₂SO₄ because H₂SO₄ has basicity of 2 while HCl has basicity of 1.
