I hope this answer is correct
O.7 kilometers is equivilent to 7 hectometers :)
Answer:
V = 177.4 L.
Explanation:
Hello there!
In this case, since this gas can be assumed as ideal due to the given data, we can use the following equation:

Thus, by solving for volume we obtain:

So we can plug in the temperature in Kelvins (537 K), the pressure in atmospheres (0.404 atm) and the molar mass (54 g/mol) to obtain:

Best regards!
Answer:
24.2 mL.
Explanation:
<em>Assuming constant temperature</em>, we can solve this problem using <em>Boyle's law</em>, which states:
Where:
We <u>input the data</u>:
- 0.98 bar * 25 mL = 1.013 bar * V₂
And <u>solve for V₂</u>:
The closest option is the second one: 24.2 mL.
