Using the van der waals equation, find the pressure exerted by 1 mole of ar gas stored in a 1.42-liter container at 300 k. given: a = 1.35l2 · atm/mol2, b = 0.0322 l/mol, and r = 0.08205 l · atm/k · mol

I’m writing this equation by memory, so I hope I’m correct. It’s been about four months since we used in in my chem class:

(P-(n^2•a)/V^2)(V-nb)=nRT

Plugging in values given:

(P-(1•1.35)/(1.42^2))(1.42-(1•0.0322))=(1)(0.0821)(300)
(P-(1.35/2.016))(1.42-0.0322)=24.63
(P-(1.35/2.016))=17.75
P=18.42 atm

The pressure exerted by the Argon would be 18.42 atmospheres.

What are the options? physical property can be color, smell, opacity, viscosity, density, infra red spectrum, melting and boiling points, attraction and repulson to magnets, etc.
