The percent error is used to determine the precision of calculations. It can be expressed as:
where:
e - the percent error,
v - experimental value (measured value),
v₁ - theoretical value,
It is given:
e = ?
v = 88 calories
v₁ = 80 calories
Thus, the percent error is:

The answer is:
The new volume is 2.84 L.
To solve the problem, we need to remember what STP means. STP means that the gas is at standard temperature and pressure, or 273.15 K (0°C) and 1 atm.
Also, we need to use the Combined Gas Law, since the temperature, the pressure and the volume are being changed.
The Combined Gas Law establishes a relationship between the temperature, the pressure and the volume of an ideal gas using , Gay-Lussac's Law, Charles's Law, and Boyle's Law.
The law is defined by the following equation:
Where,
is the first pressure.
is the first volume.
is the first temperature.
is the second pressure.
is the second volume.
is the second temperature.
So, we are given the following information:
Then, isolating the new volume, and substituting, we have:
Hence, the new volume is 2.84 L.
Have a nice day!
