Answer : The percent difference between the ideal and real gas is, 4.06 %.
Explanation : Given,
Ideal pressure (true value) = 49.3 atm
Real pressure (measured value) = 47.3 atm
The formula used to calculate percent difference is :
Percent difference = [tex]\frac{\text{True value - Measured value}}{\text{True value}} \times 100[/tex]
Percent difference = [tex]\frac{(49.3- 47.3)atm}{49.3atm}\times 100[/tex]
Percent difference = 4.06 %
Therefore, the percent difference between the ideal and real gas is, 4.06 %.
