Question

SO4 a) Lead(ll) nitrale Phe(NDal na Ph+2 b) Iron(I) chloride Fo2t + 2 C EeCls tag c) Ammonium phosphale d) Potassiurm carbonate 2CO3t aa 2t+cos 2. What is the concentration of the mamesium ions and the chloride ions in 2.5 M solution of MgCl;? Mgcl2 Mg2 20e 3. (a) Suppose 1.00 mL of 0.70 % glucose solution was diluted to 10.00 mL. (by adding water) What is the concentration of the diluted solution? (b) If 1.00 ml. of the diluted solution in step (a) was further diluted to 10.00 ml. (by adding water), what is the concentration of the solution after the 2nd dilution?

Answer 1

mach, → Mg2+ + 2t lingch give - 1 mg 2+ and 2a- l'ary Malarity of Mych = 2.5M. molarity of Mg 2+ = 2.5M i 5M molarity of t = 2x2.5 - [ 6, ал. Ман ва = mouth, 1.
