The V.D of Gas is 15. 15 g of this gas will occupy a volume of ______ cc at $$273^\circ\text{C}$$ and 1 atm.
Correct Answer: 22400
The molar mass is $$2 \times 15 = 30$$, so 15 g is 0.5 mol. At STP this would occupy $$0.5 \times 22400 = 11200\text{ cc}$$. At $$273^\circ\text{C}$$ (546 K) the absolute temperature is doubled, so the volume doubles to 22400 cc.
