What is the pressure of 1.50 moles of a gas in a 30.0L tank at a temperature of
285K?

The pressure of the gas : 1.1685 atm

In general, the gas equation can be written  

where  

P = pressure, atm  

V = volume, liter  

n = number of moles  

R = gas constant = 0.08206 L.atm / mol K  

T = temperature, Kelvin  

n=moles=1.5

V=volumes = 30 L

T=temperature=285 K

The pressure :
