Calculate the mass, in grams, of a single xenon atom (mxe = 131.29 amu ).

Mariana [72]

Answer is $2.18017\times10^{-22}gms$ .

Explanation: To calculate the mass of 1 Xe-atom , we will require atomic mass of Xe which is 131.29amu.

This atomic mass is the mass of 1 mole of 1 Xe-atom. One mole of Xe-atom is $6.022\times10^{23}$ atoms of Xe. We will use this relation to convert Mass of Xe-atom into grams.

$\frac{\text{mass of 1 atom}}{atom}=\frac{\text{mass of 1 mole of atom}}{6.022\times10^{23}atoms}$

$\text{mass of 1 atom}=\frac{\text{mass of 1 mole of atom}}{6.022\times10^{23}}$

$\text{mass of 1 Xe-atom}=\frac{131.29}{6.022\times10^{23}}$

$\text{mass of 1-Xe atom}=21.8017\times10^{-23}gms$

= $2.18017\times10^{-22}gms$

If the fugacity of a pure component at the conditions of an ideal solution is 40 bar and its mole fraction is 0.4, what is its f

yaroslaw [1]

Answer : The fugacity in the solution is, 16 bar.

Explanation : Given,

Fugacity of a pure component = 40 bar

Mole fraction of component = 0.4

Lewis-Randall rule : It states that in an ideal solution, the fugacity of a component is directly proportional to the mole fraction of the component in the solution.

Now we have to calculate the fugacity in the solution.

Formula used :

$f_i=X_i\times f_i^o$
