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

How is the number 3.91 x 10-4 expressed in regular numbers?
Semenov [28]

To convert a number without the use of the expression 10^-4 you would have to treat it like an integer line for instance on an integer line the negative is to the left and the positive number is to the right so 3.91*10^-4 means that the decimal would have to move 4 places to the left so the answer would be .000391 instead of 3.91*10^-4.


I hope this helps you :)
