That is -273 + 30 = -243 degrees celsius
Answer:
2.22 mole
Explanation:
At STP one mole of an ideal gas occupies 22.4 L of volume.
Hence,
Volume = mol × 22.4 L/mol
solving for mole,
Mole = Volume / 22.4 L/mol
Putting values,
Mole = 49.8 L / 22.4 L/mol
Mole = 2.22 mole
Answer:
The answer is
<h2>1.336 atm</h2>
Explanation:
In order to find the volume of the gas at 175 mL we use the Boyle's law formula
That's
![P _1 V _1 = P _2 V _2](https://tex.z-dn.net/?f=P%20_1%20V%20_1%20%3D%20P%20_2%20V%20_2)
where
P1 is the initial pressure
V1 is the initial volume
V2 is the final volume
P2 is the final pressure.
Since we are finding the final pressure
![P _2 = \frac{P _1 V _1}{ V _2}](https://tex.z-dn.net/?f=P%20_2%20%3D%20%20%5Cfrac%7BP%20_1%20V%20_1%7D%7B%20V%20_2%7D%20)
From the question
P1 = 0.935 atm
V1 = 250.0 mL
V2 = 175 mL
Substitute the values into the above formula and solve
That's
![P _2 = \frac{0.935 \times 250}{175} \\ = \frac{233.75}{175} \\ = 1.33571](https://tex.z-dn.net/?f=P%20_2%20%20%3D%20%20%5Cfrac%7B0.935%20%5Ctimes%20250%7D%7B175%7D%20%20%5C%5C%20%20%3D%20%20%5Cfrac%7B233.75%7D%7B175%7D%20%20%20%5C%5C%20%20%3D%201.33571)
We have the final answer as
<h3>1.336 atm</h3>
Hope this helps you
