How many moles of S2O3^2- ions are required for titration, mol?
Brand: Bleach 101
Cost of commercial bleach solution per gallon: $1.79
Density of commercial bleaching solution, g mL ^1- : 1.10 g/mL
Molarity of Na2S2O3, M=0.100mL
Volume of diluted bleaching solution titrated, mL: 25.00
Final Buret reading mL: 14.5
Initial Buret reading mL: 0.2
Volume of Na2S2O3 solution used: 14.3
Number of moles of S2O3^2- : ????
0.100 mol/L x ____L x 1/1
M Na2S2O3 x Vx 1 molS2O3^2-/1mol Na2S2O3
(Guessing these are same calculations?)
Thanks to those who help. I cannot solve the rest unless I have this equation figured out I originally gotten 0.0014 but my lab partner tells me that it's 0.572 but that doesn't seem to follow the equation.
