Start by writing the atoms balance:
Now, determine the change of oxidation states:
has oxidation state 0, so each N has to gain 3 electrons to become
.
That, means that you need 6 electrons to balance the charges, resulting in:
And the answer is 6 mole of electrons.
Answer:
1.3 M
Explanation:
1 mole= Concentration * Volume
1 mole=C*0.75 L
C=1.3 M
