Pregunta: A BaCl2*2H2O solution was prepared as follows: 4.57 (+-0.02) g of BaCl2*2H2O (Formula weight=244.0(+-0.3)g/mol), was dissolved in 50.0mL of distilled water, in a 500 mL beaker. If this solution is transferred to a 250.00 n(+-0.12) mL volumetric flask and made up to the mark with distilled water. Determine the concentration of the resulting solution and the
