Ch 12.2 Help

no typo.. I'm a distant relative of Avogadro

I am still having trouble with Question 3. My work:

1.1087 atm
2.595 L
24.59 C

(((1.1087*101305)*(2.595/1000))/(8.31*(273.15+24.59))*6.022e²³)/10²⁰

The answer I put: 70.9390

Does 101325 really make the difference in the number?

EDIT: Found out it really doesn't.

It's supposed to be
((Patm*101305)*(L/1000)*6.02*10^23) then divide all of this by (celsius temp+273.15)*(8.13) to get something around 10^23 or 10^22 then divide by 10^20

Doing that I get a value of 112.xxxx

I don't know if one of the constants I'm using is wrong or what.

I guess I can sacrifice 1 point.
