States of matter — practice question

Use of the Data Booklet is relevant for this question. Iodine is a black, lustrous, non-metallic solid and a member of Group VII. When heated, it sublimes readily to form a purple vapour. A sample of iodine vapour with a mass of $6.35\,\text{g}$ occupies a volume of $1.247\,\text{dm}^3$ when the temperature is kept constant and the pressure is $1.00 \times 10^5\,\text{Pa}$. Assuming iodine vapour behaves as an ideal gas, what is the temperature of the iodine vapour?

  • A$300\,\text{K}$
  • B$600\,\text{K}$
  • C$300\,000\,\text{K}$
  • D$600\,000\,\text{K}$
