If a student dissolves 5.082 g of NiCl2 * 6H2O in water in a 250.0 ml flask,
What is the solution's concentration in g/L? (show all work)
What is the solution's concentration in mol/L? (show all work)

Its your homework assignment. Not ours... unless you show us your answers first and why you think they are right. Nobody here will can help you according to the site rules.

HINT:- Find the molar mass of NiCl2 * 6H2O and then proceed.

I think this would be the answer - is this correct
If a student dissolves 5.082g of NiCl2⋅6H2O in water in a 250.0 mL flask,


What is the solution's concentration in g/L? 5.082g /.25L = 20.33 g/L
what is the solution's concentration in mol/L? 5.082g X (1 mole / 237.7 molar mass) = .021 mole .021/.25=.084 mol/L

If that student then removed 5.00ml of that solution and diluted it to 50.00 ml, what would the new solution's concentration be in g/L? Taking out 5 mL. Have to find out how many grams are each mL. Convert g/L to g/ml 20.33/1000 = .02033 g/mL .02033 X 5.00 mL = 0.1016 g/mL now convert mL to L by dividing by 1000 0.1016/1000 = .0001016 g/L new solution is 50 mL convert to liters 50/1000 = .05L 0.0001016 g/L/.05 = .002032 g/L
