Respuesta :
The volume of the system is found to be 5.097L and the % error is found to be 13.2%.
Every three-dimensional item requires some amount of space. The volume of this space is measured. Volume is defined as the space occupied by an item inside the confines of three-dimensional space. It is also known as the object's capacity. Volumes change depending on the form.
The absolute value of the difference between the measured and actual values is divided by the actual value and multiplied by 100 is the % error. Percent mistakes indicate the magnitude of your errors while measuring anything in an experiment. Smaller numbers of % error indicate that you are getting nearer to the acceptable or true value.
Given:
P = 12atm
n = 2 moles
T = 100℃ = 100 + 273 = 373K
To find:
(a) V = ?
(b) % error = ?
Formula:
PV = nRT
% error = (experimental – actual) / actual x 100
Calculations:
(a) V = nRT/P
V = 2 x 0.082 x 373 / 12
V = 5.097L
(b) % error = (5.097 – 4.5) / 4.5 x 100
% error = 0.597 / 4.5 x 100
% error = 0.132 x 100
% error = 13.2%
Result:
The system’s volume is 5.097L and the % error is 13.2%.
