Question

Which gas law would you use for the following problem: What pressure is required to hold 8.0 moles of oxygen gas in an 8.0 L container at a temperature of 80 degrees Celsius?

Boyle’s Law

Charles’ Law

Combined Gas Law

Ideal Gas Law

Answer 1

Ideal Gas Law ( PV = nRT)

Step-by-step explanation:

Using the Ideal Gas Law, we have; PV = nRT

Where P= Pressure = ?

V= Volume = 8.0 L

n = moles = 8.0

R = Gas constant = 0.0821 L.atm/mol/K

T = 80° c + 273 = 353.15K

Therefore Pressure would be; P = nRT/ V = 8 x 0.0821 x 353.15 / 8 = 28.9atm
