States of matter — practice question

The gas laws may be represented by the ideal gas equation, $pV = nRT$. A vessel with a volume of $7.00 \times 10^{-3}\,\text{m}^3$ contains $0.960\,\text{g}$ of oxygen gas at a temperature of $30^{\circ}\text{C}$. Assume the gas behaves as an ideal gas. What is the pressure in the vessel?

  • A$1.07\,\text{kPa}$
  • B$2.14\,\text{kPa}$
  • C$10.8\,\text{kPa}$
  • D$21.6\,\text{kPa}$
