50 mL of a chlorofluorocarbon gas effused through a porous barrier in 157 seconds. The same volume of argon effused in 76 second

Anna11 [10]

Answer:

$CCl_{2}FCF_{3}$

Explanation:

To solve this equation we can use Graham's Law of effusion to calculate the molar mass of the chloroflourocarbon

$\sqrt{\frac{M_{1} }{M_{2} } } = \frac{t_{1} }{t_{2} } \\\\\sqrt{\frac{M_{1} }{39.948 } } = \frac{157 }{76}\\\\\\M_{1} = 170.477\\$

Which chloroflorocarbon has this molar mass?

C2Cl2F4

the temperature of a balloon rises from 275 degrees k to 395 degrees k, what would the ending volume be if it started at 5 L

Airida [17]

<h3>Answer:</h3>

7.182K

<h3>Explanation:</h3>

From the question we are given;

Initial temperature, T1 = 275 K
Final temperature, T2 = 395 K
Initial volume, V1 = 5 L

We are required to calculate the final volume, V2

Charles's law is the law that relates the volume of a gas and its temperature.
It states that the volume of a fixed mass of a gas and its absolute temperature are directly proportional at a constant pressure.
Therefore;

$\frac{V1}{T1}=\frac{V2}{T2}$

To calculate, V2 we rearrange the formula;

$V2=\frac{V1T2}{T1}$

$V2=\frac{(5L)(395K)}{275}$

$V2=7.182K$

Therefore, the ending volume will be 7.182K
