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