Chemistry question

A 10.0 L flask contains 64 g of oxygen at 27 °C (assume O2\mathrm{O_2} gas is behaving ideally). The pressure inside the flask in bar is (given R=0.0831 L bar K−1 mol−1R = 0.0831\ \mathrm{L\,bar\,K^{-1}\,mol^{-1}}):

  1. A.4.9✓
  2. B.2.5
  3. C.498.6
  4. D.49.8

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
