qqp question1: If 0.5 moles of BaCl2 is mixed with 0.2 moles of Na3PO4, the maximum number of moles of Ba3(PO4) 2 that can be formed is : a) 0.70 b) 0.50 c) 0.30 d) 0.10. I believe answer should be 0.16 but there's no such option. What do I do now? question2: At 25°C the solubility product of AgI is 1.0*10^-16mol^2/lit^2. Then what is the solubility of AgI in 10^-4N solution of KI?
