The Chloride in a Sample of BaCl₂ Is Precipitated with 50.0

Multiple Choice

The chloride in a sample of BaCl₂ is precipitated with 50.0 mL of 0.100 M AgNO₃.The excess silver nitrate is titrated with 5.25 mL of 0.125 M k₂CrO₄.Calculate the mass of the barium chloride sample. BaCl₂(aq) + 2 AgNO₃(aq) → 2 AgNO₃(aq) + Ba(NO₃) 2(aq)
2 AgNO₃(aq) + k₂CrO₄(aq) → Ag2CrO₄(aq) + 2 KNO₃(aq)
