Question

What is the density of a sample of argon gas at 53∘C and 889mmHg ?

Answer 1

You're missing some information, I think. Density requires both: \(\sf \color{}{density =\frac{mass}{volume}}\)

Answer 2

You can assume any mass (say 1 g) then find the volume it would occupy at those conditions (using the ideal gas law, PV=nRT). Then, apply the density formula now that you have the m and V parameters.

Answer 3

You're too much for me right now @aaronq
