What is the temperature in c of a sample of 4.75 moles of co2 gas at a pressure of 0.998 atm that is placed in a container with a volume of .125 l?

Explanation:

We can use the Ideal Gas Law to calculate the temperature.

pV = nRT

Data:

p = 0.998 atm

V = 0.125 L

n = 4.75 mol

R = 0.082 06 L·atm·K⁻¹mol⁻¹

Calculation:

T = (0.320 – 273.15) °C = -272.83 °C

Note: This is an impossible situation. CO₂ solidifies at -78.5 °C.

If CO₂ were an ideal gas, the calculated temperature would be

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
