(6a): Write a balanced equation for the reaction between Ba(NO3)2 (aq) and Na2SO4(aq). Include the phases. Hint: swap ion partners and check solubility rules. /(6b): If 68.44g of Na2SO4 was needed to react with 41.33mL of Ba(NO3)2, what was the concentration of the Ba(NO3)2 ? (6c): If 125.0mL of 0.1185MNa2SO4 was react with 41.33mL of 0.3114MBa(NO3)2, how many grams of the solid product can be produced
