. Laughing gas is used by dentists as an anesthetic. If a 10.0 L tank of laughing gas contains 1.26 moles N2O at 23°C, what is the pressure (mmHg) in the tank?

Respuesta :

Answer:

Pressure = 2324.08 mmHg

Explanation:

We are given

Volume = 10L

No of moles = 1.26

Temperature = 23degree = 296k

Pressure = ?

using the ideal gas equation

PV = nRT

P = nRT/V

P = [tex]\frac{1.26*0.082*296}{10}[/tex]  = 3.058atm

1 atm = 760mmHg

Pressure = 2324.08 mmHg
