Concept introduction:
Ideal gas is a hypothetical gas for which the assumptions are that the particles have no interaction and occupy negligible space and obeys
The expression relating the pressure, P, volume, V with number of moles, n and temperature, T of an ideal gas is:
Where R is Universal gas constant.

Answer to Problem 20STP
The pressure of the gas is
Explanation of Solution
Given:
Temperature,
Volume,
Converting the temperature from degree Celsius to Kelvin:
Now, in order to determine the pressure of the gas, the equation (1) is rewritten as:
Value of R used is
Substituting the values in above equation:
Since, the pressure of the gas is
