How many atoms in 1 m^3 of N_2O at "STP"?

Explanation:

In 22.4 L at "STP", there are N_A gaseous particles, where N_A = "Avogadro's Number ", 6.022xx10^23*mol^-1.

So in 1*m^3, there are (1000*L)/(22.4*L*mol^-1) = 44.6*mol" *N_2O

So "number of atoms" = 44.6*molxxN_Axx3*"atoms" = " A lot of atoms".
