Substances that give ions when dissolved in water are called electrolytes. They can be divided into acids, bases, and salts because they all give ions when dissolved in water. These solutions conduct electricity due to the mobility of the positive and negative ions, which are called cations and anions respectively.
Electrolytes are composed of free-moving Charged Particles, i.e. ions. When a PD is applied across the electrolytes, the +ve ions move towards the -ve terminal and gain electrons to become neutral atoms, the opposite happens with the -ve atoms. Electrolytes lose their conductivity over time since they liberate some of the constituents of the electrolyte as gases or metals that settle at the bottom.

Answer:
The pressure of 0.5 mole of nitrogen gas=
Given:
Moles of nitrogen gas=0.5mole
Volume of nitrogen gas=5L
Temperature of nitrogen gas=203K
To Find:
Pressure of 0.5g mole of nitrogen gas
<u>Step by Step by Explanation:</u>
Formula used for calculating the pressure of a gas is achieved through ideal gas equation
According to Ideal Gas;
From this above equation, pressure can be calculated as
Where P=Pressure of the gas
N=number of moles=0.5moles
R=Gas constant
V=Volume of nitrogen gas in litres=5L
T=Temperature of nitrogen gas=203K
Substitute all the values in the above equation we get
Result:
Thus the pressure of 0.5 mole of nitrogen gas is <u></u><u>
