Question

A chemist makes 330 ml of nickel(II) chloride (Nici,) working solution by adding distilled water to 50.0 ml of a 4.68 M stock solution of nickel(II) chloride in water Calculate the concentration of the chemist's working solution. Round your answer to 3 significant digits.

Answer 1

* Given 5o.om 1 of 4.68M Nich soluhon is diluted to total 330 ml solution. The modality of this solution is not known We have, MV) - 12V - Mi 4.68M , V = 50.0ml, M2= ? V2=330 Oml M₂ = Movi = 4.68M X 50.00 330.0m M2 = 0.709 M. Thu Connonohon of working 0.709 M ñ 0.71M 6 Solunos Is
