Problem

Argon gas (

M=39.9\,\text{g}\,\text{mol}^{-1}

) is stored at a pressure of

1.20\,\text{atm}

and a temperature of

45^{\circ}\text{C}

. What is the density of the gas in

\text{kg}\,\text{m}^{-3}

? a)

13\,\text{kg}\,\text{m}^{-3}

1.8\,\text{kg}\,\text{m}^{-3}

0.73\,\text{kg}\,\text{m}^{-3}

1.5\,\text{kg}\,\text{m}^{-3}
