Use the ideal gas law PV = nRT
convert the 2.78 g of Ne to moles for "n"
change the -10 degrees C to kelvin for "T"
use the 5.00 L for "V"
use 0.082 for "R"
Solve for P in atmospheres

ill tell you how to do it. do you know the formula-
pV= nRT
p= pressure
V= volume
n= number of moles
R= universal gas constant
T= temperature in Kelvins
it might help if you practise the formula yourself
R is not .082 like the guy above says. i always thought that the gas constant was 8.31

P=nRT/V
