Four balloons, each with a mass of 10.0 g, are inflated to a volume of 20.0 l, each with a different gas: helium, neon, carbon monoxide, or nitrogen monoxide. if the temperature is 25.0°c and the atmospheric pressure is1.00 atm, what is the density of each filled balloon? (note: the density of the filled balloon refers to both the contents of the balloon and the balloon itself.)

Pressure ,P = 1 atm

Volume, V = 20.0 L

R = 0.0821 atm L/mol K

Balloon 1

Density of balloon 1 =

Balloon 2

Density of balloon 2=

Balloon 3

Density of balloon 3 =

Balloon 4

Density of balloon 4=

samuel de champlain. in 1608, king henry iv sponsored pierre dugua, sieur de mons and samuel de champlain as founders of the city of quebec with 28 men. this was the second permanent french settlement in the colony of canada.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
