If 12.5 G of (NH4)3PO4 is dissolved in enough water to make 575mL of solution. What is the molarity of NH4+ in
[From: ] [author: ] [Date: 11-05-05] [Hit: ]
5g / 149g/mole = 0.0.0839moles x 3 = 0.0.252moles / 0.575L = 0.......
Please help!

12.5g / 149g/mole = 0.0839moles (NH4)3PO4
there are 3 moles NH4+ in 1 mole (NH4)3PO4
0.0839moles x 3 = 0.252moles NH4+
0.252moles / 0.575L = 0.438M
