Hydrogen chloride gas is shipped in a container under 5,100 mm Hg of pressure that occupies 20.1 liters at 29°C. How many liters
Agata [3.3K]

The gas will occupy 120 L at STP.

We can use the <em>Combined Gas Laws</em> .

In 1982, chemists redefined <em>STP</em> as <em>1 bar</em> and 0 °C (273.15 K).

<em>p</em>_1 = 5100 mmHg × (1 atm/760 mmHg) × (1.013 bar/1 atm) = 6.798 bar

<em>T</em>_1 = (29 + 273.15) K = 302.15 K

<em>p</em>_1<em>V</em>_1/<em>T</em>_1 = <em>p</em>_2<em>V</em>_2/<em>T</em>_2

<em>V</em>_2 = <em>V</em>_1 × <em>p</em>_1/<em>p</em>_2 × <em>T</em>_2/<em>T</em>_1

= 20.1 L × (6.798 bar/1 bar) × (273.15 K/302.15 K) = 120 L
