Question

At which of the four conditions, the density of nitrogen will be the largest?

• A. STP
• B. 273 K and 2 atm
• C. 546 K and 1 atm
• D. 546 K and 2 atm

Answer 1

Answer: (B)

273 K and 2 atm

Answer 2

Density of a gas is given ρ = $\frac{PM}{RT}$. Obviously the choice that has greater $\frac{P}{T}$ would have greater density.
