Accepted Answer
The molarity of the stock Mn²⁺ ions is 0.0288 MBased on the dilution formula;The molarity of A is 0.00144 MThe molarity of B is 0.0000576 MThe molarity of C is 0.000001152 MWhat is the molarity of a solution?The molarity of a solution is the number of moles of a solute dissolved in a given volume of solution in liters.Molarity = number of moles/volumeThe molarity of the stock solution is:moles of Mn²⁺ ions = mass / molar massmolar mass of Mn²⁺ ions = 55.0 g/molmoles of Mn²⁺ ions = 1.584 / 55moles of Mn²⁺ ions = 0.0288 molesmolarity of Mn²⁺ ions = 0.0288 / 1molarity of Mn²⁺ ions = 0.0288 MThe dilution formula is used to determine the molarities of A, B, and C.C₁V₁ = C₂V₂C₂ = C₁V₁ / V₂Where;C₁ = initial molarityV₁ = initial volumeC₂ = final molarityV₂ = final volumeMolarity of A = 50 * 0.0288 / 1000Molarity of A = 0.00144 MMolarity of B = 10 * 0.00144 / 250Molarity of B = 0.0000576 MMolarity of C = 10 * 0.0000576 / 500Molarity of C = 0.000001152 MLearn more about molarity at: https://brainly.com/question/17138838#SPJ1
