Find the fugacity coefficient of a gaseous species of mole fraction 0.4 and fugacity 25 psia in a mixture at a total pressure of
Oksana_A [137]

<u>Answer:</u> The fugacity coefficient of a gaseous species is 1.25

<u>Explanation:</u>

Fugacity coefficient is defined as the ratio of fugacity and the partial pressure of the gas. It is expressed as \bar{\phi}

Mathematically,

\bar{\phi}_i=\frac{\bar{f_i}}{p_i}

Partial pressure of the gas is expressed as:

p_i=\chi_iP

Putting this expression is above equation, we get:

\bar{\phi}_i=\frac{\bar{f_i}}{\chi_iP}

where,

\bar{\phi}_i = fugacity coefficient of the gas

\bar{f_i} = fugacity of the gas = 25 psia

\chi_i = mole fraction of the gas = 0.4

P = total pressure = 50 psia

Putting values in above equation, we get:

\bar{\phi}_i=\frac{25}{0.4\times 50}\\\\\bar{\phi}_i=1.25

Hence, the fugacity coefficient of a gaseous species is 1.25

The total number of sodium atoms in 46.0 grams of solution is?
USPshnik [31]
Molar mass Na = 23g/mol
46g = 456/2 = 2mol
1mol = 6.022*10^23 atoms
2mol = 2*6.022*10623
= 1.204*10^24 atoms

What atom has 8 protons and 10 electrons?
Lorico [155]

Answer:

In your case, you have 8 protons and 10 electrons. This means that the atom will carry a total 2 xx (1-) = 2- net charge. Therefore, you are dealing with an anion that carries a 2- net charge, i.e. it has two more electrons than it does protons.
