Question

What is the molar quantity of `SO_2` in a `1.0*dm^3` volume of same at a temperature of `300*K`, and a pressure of `740*mm*Hg`?

Answer 1

`"Number of gas molecule"=2.4xx10^22`

Explanation:

We solve for `n` in the Ideal Gas Equation....

`n=(PV)/(RT)=((740*mm*Hg)/(760*mm*Hg*atm^-1)xx1.0*dm^3)/(0.0821*(dm^3*atm)/(K*mol)xx300*K)`

And we gets an answer `-=0.0395*mol`...

And we multiply this number by the `"Avocado number"`....

`=0.0395*molxx6.022xx10^23*mol^-1=??`
