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?

Answer 1

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.
\[P = \frac{ nRT }{ V }\]

Answer 2

Pressure needs to be in atm.

Answer 3

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