What is the concentration (in ppm) of Mn7+ in a 0.00300 M KMnO4 solution?  Note:  for dilute aqueous solutions, 1 ppm = 1 mg/L.
aleksklad [387]

We know that there is 1 mole of Mn for every 1 mole of KMnO4, therefore the molarity of Mn is similar with KMnO4:

Mn = 0.00300 M

Molar mass of Mn is 54.94 g / mol. Molarity (M) is moles / L, therefore:

Mn = (0.00300 moles / L) * (54.94 g / mol) * (1000 mg / g)

<span>Mn = 164.82 mg / L = 164.82 ppm</span>

Natasha2012 [34]

Answer:

  • <u><em>Option A.) 2 ppm</em></u>

Explanation:

<u><em>60 particles in 30 million</em></u> can be expressed as a fraction:

  • \frac{60}{30million}

And, dividing both numerator and denominator by 30, that can be simplified as:

  • \frac{2}{1million}

That means 2 particles of sulfur dioxide in 1 million particles of sample, which is 2 parts per million or<u> 2 ppm</u>, which is the option A.
