What is the density of one mole of $He$ (molar mass $= 4 \ g \ mol^{-1}$) at $300 \ K$ and a pressure of $0.82 \ atm$? $(R = 0.082 \ L \ atm \ mol^{-1} \ K^{-1})$

• A
  $1.33 \times 10^{-2} \ g \ mL^{-1}$
• B
  $1.33 \times 10^{-2} \ g \ L^{-1}$
• C
  $1.33 \times 10^{-1} \ g \ L^{-1}$
• D
  $1.33 \times 10^{-1} \ g \ mL^{-1}$
