Answer:
The answer to your question is 308.1 g of KmNO₄
Explanation:
Data
Volume = 6 L
Concentration = 0.325 M
Molar mass of Potassium permanganate = 39 + 55 + (16 x 4) = 158 g
Process
1.- Calculate the moles of KMnO₄
Formula
Molarity = moles/volume
moles = molarity x volume
moles = 0.325 x 6
moles = 1.95
2.- Calculate the grams of KMnO₄
158 g KMnO₄ ------------------ 1 mol
x ------------------ 1.95
x = (1.95 x 158)/1
x = 308.1 g
In
Methyl Amine the Nitrogen atom is attached to two Hydrogen Atoms and one Methyl (CH₃-) group. From
Lewis structure it is shown that the Nitrogen atom also contains a
lone pair of electron.
So,
According to
Valence Shell Electron Pair Repulsion (VSEPR)
Theory, those central atoms which have four electron pairs and all of them are bonding electron pairs gives
Tetrahedral Geometry.
Methylamine also contains four electron pairs, but out of four only
three are bonding pair electrons and
one lone pair electron. Now, due to presence of lone pair of electron (which has
greater repulsion effect than bonding electron pair) the bond angle between H-N-H will decrease from
109° to 107° and results in the formation of <span>
Trigonal Pyramidal geometry as shown below,</span>
