I am working on a redox stoichiometry lab. I need to calculate the moles NaBO3*4H2O.
Mass=1.0133g in 100mL solution
In my experiment I used 9.98mL and titrated in with KMnO4.
I'm really confused about how to calculate the moles. Thanks for any help!!!!
Write the equation and balance it. Do that first.
I calculated the M of NaBO.... at 6.59x10^-3 for the mass I measured. I have a chart of measurements where I used 9.98mL out of 100mL of solution that I made. I was given the equation
(mass Na.../molar mass Na...)*(volume Na.../volume total solution)
the balanced equation I'm totally stuck.
I need more information than that. For moles NaBO3.3H2O = grams/molar mass.
