Question

If 79.5 mol of an ideal gas occupies 99.5 L at 39.00 °C, what is the pressure of the gas?
and 
If 57.5 moles of an ideal gas is at 6.51 atm at 90.70 °C, what is the volume of the gas?

rushwr · Answer

For both situations use the below equation
$$PV =nRT$$
P= pressure in pascals
V= Volume in cubic metres
n= no. of moles
R = universal gas constant = 8.314 JKmol^-1
T= temperature in kelvin. 
$$P = \frac{ nRT }{ V }$$

jhannybean · Answer

Pressure needs to be in atm.

rushwr · Answer

I thought it should be in pascals ! that is Nm^-2
