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)

Zarrin [17]

Answer:

$r=215pm$

$N_{Mn}=20$

Explanation:

From the question we are told that:

Edge length of the unit cell $l=608pm$

Generally the equation for The relationship between edge length and radius is mathematically given by

$4r=\sqrt{2a}$

Therefore

$4r=\sqrt{2*608}$

$r=\frac{\sqrt{2*608}}{4}$

$r=215pm$

From the question we are told that:

Density $\rho=7.297$

Edge length of $l=630.0 pm=>630*10^-{10}$

Therefore Volume is given as

$V=l^3$

$V=630*10^-{10}^3$

$V=2.50047*10^{−22}$

Generally the equation for Mass is mathematically given by

$m=Volume*density$

$m=V*\rho$

$m=2.50047*10^{−22}*7.297$

$m=1.83*10^{-21}g$

Therefore Molarity is given as

$n=\frac{M}{Molar M}$

$n=\frac{1.83*10^{-21}g}{55}$

$n=3.32*10^{-23}$

Finally The atoms in a unit cell is

$N_{Mn}=Moles*Avogadro\ constant$

$N_{Mn}=3.32*10^{-23}*6.023*10^{23}$

$N_{Mn}=20$

As the ball falls, its energy will decrease and its energy will increase

svlad2 [7]

Answer: As an object falls its potential energy decreases, while its kinetic energy increases. The decrease in potential energy is exactly equal to the increase in kinetic energy.
