Question

Use graham's law to calculate how much faster fluorine gas, f2 , will effuse than chlorine gas,br2, will the molar mass of f2=38.0; the molar mass of br2=160

Answer 1

Fluorine gas (F2) will effuse approximately 0.487 times faster than chlorine gas (Br2).

Step-by-step explanation:

To calculate how much faster fluorine gas (F2) will effuse than chlorine gas (Br2), we can use Graham's law. Graham's law states that the ratio of the effusion rates of two gases is inversely proportional to the square root of their molar masses.

Let's calculate the ratio using the given molar masses:

Ratio = sqrt(molar mass of F2) / sqrt(molar mass of Br2)

Ratio = sqrt(38.0) / sqrt(160)

Ratio = 6.164 / 12.65 = 0.487

Therefore, fluorine gas (F2) will effuse approximately 0.487 times faster than chlorine gas (Br2).

Answer 2

Fluorine gas effuses 1.37 times faster than chlorine gas

calculation
Rate of F2/rate of Cl2 =√ molar mass Cl2 / molar mass F2
rate of F2/Rate of Cl2 = √1.868

rate of F2/rate of Cl2 =√ 71/38 = 1.37 times faster than chlorine
