If $$\mathrm{N}_2$$ gas is compressed at 2 atmosphere from 9.0 L to $$3.0 \mathrm{~L}$$ at $$300 \mathrm{~K}$$, find the final pressure at same temperature.

What is the volume in $$\mathrm{dm}^3$$ occupied by $$3 \mathrm{~mol}$$ of ammonia gas at STP?

Which of the following formulae is used to determine compressibility factor for measurement of deviation from ideal behaviour?

What is the volume of 1 mole real gas at STP $$\left(V_0=22.4 \mathrm{~dm}^3\right)$$, if compressibility factor of real gas is 1.1 at STP?
