Mass/volume
In order to find density, you need to divide mass/volume
Answer:
Fill in the blanks: IONIC compounds break up into ANIONS and CATION in solution, which can move freely and carry an ELECTRICAL current.
To solve this problem all you would have to do is to use the stoichiometric ratio of 1 mol of Oxygen would react with 2 mol of H2O, to find moles of water produced.
1 mol of O2 = 2 mol of H2O
20 mol of O2 = 40 mol of H2O.
The moles of water produced would be 40 moles.
Well none since molecules are a group of two or more atoms electrically bonded with one another. However, there are gases that does not naturally bond due to their stability and can be found in nature as pure elements. But these are not considered as molecules.
(By the way, these gases are the noble gases that can be found on the last column of the periodic table)

Explanation:
Both oxygen and dinitrogen (1) oxide are known to rekindle a glowing splint. However, oxygen is an odorless gas while dinitrogen (1) oxide has a faint smell and has an effect on the central nervous system.
Also, the combustion of dinitrogen (1) oxide produces brown fumes of nitrogen IV oxide.
Finally, when dinitrogen (1) oxide and oxgen are both heated with copper, residual nitrogen gas is left with dinitrogen (1) oxide while no residual gas is left with oxygen.
