Answer:
30 liters
Explanation:
Since a pressure, volume, and temperature is given, this problem involves the combined gas law:
1. First, identify the given values. Make sure they are all the same units, and temperature is always in Kelvin.
<em>Your initial values:</em>
P1 = 12 atm
V1 = 23 L
T1 = 200 K
<em>Your final values:</em>
P2 = 14 atm
V2 = ?
T2 = 300 K
2. Now, plug it into the combined gas law formula. If it is easier for you, then you can rearrange the formula for V2.
3. Lastly, solve for V2.
1.38*300 = 14V2
414 = 14V2
V2 = 29.57142857142857
With sig figs, your final volume would be: 30L
Answer: 498.51mmHg
Explanation:
First let us analyse what was given from the question:
T1 = 425K
T2 = 275.15K
P1 = 770 mmHg
P2 =?
Using the general gas equation
P1V1/T1 = P2V2/T2
But we were told from the question that the volume is constant. So, our equation becomes:
P1/T1 = P2/T2
770/425 = P2 /275.15
Cross multiply to express in linear form:
P2 x 425 = 770 x 275.15
Divide both side by 425, we have:
P2 = (770 x 275.15) /425
P2 = 498.51mmHg
