The density of the gas can be given by the mass of the substance and its volume. A 4084 gms of ammonia has a volume of 5.99 L.
<h3>What is STP?</h3>
STP is the condition at which the temperature and the pressure of the gas are at the normal and standard conditions.
The density of the ammonia = 681.9gm/L
The mass = 4084 gm
The volume is calculated as:
V = Mass ÷ Volume
= 4084 ÷ 681.9
= 5.99 L
Therefore, at STP the volume of ammonia is 5.99 L.

Hello!
In this case, when looking over the chemical formula of a compound formed when two elements interact, we need to realize about their location in the periodic table; thus, since lithium is a metal and oxygen a nonmetal, we infer lithium turns out the cation and oxygen the anion. Moreover, as the oxidation state of lithium is 1+ and that of oxygen is 2-, we can set up the chemical formula as follows:

Best regards!
Answer:
Sodium chloride is an ionic compound which makes it stronger and have a higher melting and boiling point. Candle wax is a covalent compound so it has a low melting point.
