Answer 3

Thank you!!! :D.

Answer 4

\[100mL \left( 1L/1000mL \right) \left( 0.1 mol/ L \right) (mol/molar mass)\]

Answer 5

Oxidation numbers: Oxygen, usually has a -2 oxidation state. Therefore, N must have, so that the oxidation numbers equate to 0, a +2 oxidation number.

Answer 6

0.585grams.
