Question- A solution, in which the magnesium concentratio is 50mg/L, is needed. The source of magnesium ions is magnesium chloride. If 1.5L of the solution is needed, what weight of magnesium chloride must be weighed out? (FW of Mg is 24.305g/mol , and MgCl2 is 95.211g/mol.)
Part B:
If 10.00mL of the above solution (50mg/L mg2+) is pipeted into a 100mL volumetric flask and diluted to the mark with DI water, and then 5ml of that solution is pipeted into a 250 ml volumetrick flask and diluted to the mark with DI water, what is the concentration of magnesium in the final solution in ppb?
I need proficient help to working out this problem
