Chemistry math? Please help i dont get it!!!!!?
For chemistry hw, i had to work out a couple of problems. However, I DONT UNDERSTAND ANY OF IT! Please help me by EXPLAINING how to do the problems below. I want to know how to DO IT, not just the answers. Thank you. The numbers below are in subscript. I dont even understand what the questions are asking.
1) How many moles of Pb(NO3)2 must be added to a 0.10 L of solution that is 1.0 M in MgCl2 and 1.0 M in KCL? The compound PbCl precipitates.
2) When 50.0 mL of 1.0 M AgNO3 is added to 50.0mL of 0.50M HCl a precipitate of AgCl forms. After the reaction is complete, waht is the concentration of silver ions in the solution?
