Answer:
A gas made up of homonuclear diatomic molecules escapes through a pinhole .533 times as fast as Ne gas. Write the chemical formula of the gas.
Molar mass of Ne gas is 39.1 g/mol
.533= sqrt(39.1/x)
Sq (0.533) = 20.18/x
0.284 = 20.18/x
x = 71.034 g/mol
Where the chlorine has a molar mass of = 35.5g and molar mass of Cl2 gas = 2 × 35.5 = 71 g/mol
Explanation:
Graham's law: Rate1/Rate2 = sqrt(M2/M1) where M is the molar mass
Thus we have (Rate of x)/(Rate of Ne) = sqrt((Molar mass of Ne)/(Molar mass of x))
From the question (Rate of x)/(Rate of Ne) =0.533
and sqrt((Molar mass of Ne)/(Molar mass of x)) = sqrt(39.1/(Molar mass of x))
.533/1= sqrt(39.1/x)
Sq (0.533) = 20.18/x
0.284 = 20.18/x
x = 71.034 g/mol
Hence a compatible gas is chlorine Cl2 with molar mass of
71 g/mol
Answer:
science is pointless and you will never need it so just get thru the class and let it go.
