A sample of an Iron Oxalato complex salt weighting 0.13 grams requires 32.74 mL of 0.01 M KMnO4 to turn the solution a very light pink color at the quivalence point. Calculate the number of moles of KMnO4 added.

The number of moles of added are 0.0003

Explanation:

To calculate the number of moles for given molarity, we use the equation:

    .....(1)

Molarity of solution = 0.01 M

Volume of solution = 32.74 mL

Putting values in equation 1, we get:

Thus the number of moles of added are 0.0003

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
