Question

what is the total number of carbon atoms contained in 22.4 liters of CO gas STP?
A. 1.00
B. 0.500
C. 3.01 x 10^23
D. 6.02 x 10^23

Answer 1

1 CO molecule has 1 Carbon atom.

Key Point: We know at STP, one mole of a gas occupies 22.4 L ( you can find this by solving PV = nRT. But it is better to remember it.

so 22.4 L of CO gas is one mole of CO gas.

but we know,

1 mole molecule

= Avogadro number of molecules

= 6.02 x 10^23 number of molecules

therefore 22.4 L of CO gas contains 6.02 x 10^23 number of atoms.

Here you go fam, hope you have understood it. if not tell me

please appreciate my hard work. ;-)
