Hi. This is the web2.0calc.com forum, where you can discuss mathmatical problems. However, I'm afraid I'm not clear on the matter. I assume that they are paid by governmental subsidies and companies.
Hope this helps.
PV = nRT The Universal (or IDEAL) gas law
V = 5 liters
n = 4.65 moles
T = 39.3 C = 312.45 K
R = ideal gas constant = 0.082 057 338(47)L atm mol−1 K−1
Plug in these values and solve for P (pressure) ....in atmospheres
