Question

at which of 4 conditions density of nitrogen gas will be largest?

Answer 1

at 35.4 K at which nitrogen achieves allotropic form.

Answer 2

Answer:

(B) 273 K and 2 atm

Explanation:

Ideal Gas Equation:

PV = nRT

Let d be the density of the gas, then

d = m/V

V = m/d

Now, P(m/d) = nRT

d = Pm/nRT

In this equation, m, n, and R are constant

Therefore, value of d directly depends upon the value of P/T

From the given option, clearly option (B) gives us the highest value of density.

(since at STP, T=273K and P=1atm)
