How many oxygen molecules are in 22.4 liters of oxygen gas at 273k and 101.3kpa?

How many oxygen molecules are in 22.4 liters of oxygen gas at 273k and 101.3kpa

First solve the number of moles of the oxygen gas by using the ideal gas equation:

PV = nRT

Where n is the number of moles

n = PV/RT

n = (101 300 Pa) (22.4 L) (1 m3/1000 L ) / ( 8.314 Pa m3 / mol K) ( 273 K)

n = 1 mol O2

the number of molecules can be solve using avogrados number 6.022x10^23 molecule / mole

molecules of one mole O2 = 6.022x 10^23 molecules

oxygen molecules are in 22.4 liters of oxygen gas at 273 K and 101.3 kPa.

Explanation:

Pressure of the oxygen gas = P = 101.3 kPa = 1.000 atm

1 atm = 101.3 kPa

Volume of oxygen gas = V = 22.4 L

Temperature of the oxygen gas = T = 273 K

Moles of oxygen gas = n

(ideal gas )

molecules/atoms

Number of oxygen molecules : N

molecules

oxygen molecules are in 22.4 liters of oxygen gas at 273 K and 101.3 kPa.

i know insulin is primary but i dont know the others im sorry

explanation:

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
