Question

The ideal gas constant, R has several different values that could be used. Which quantity causes these differences?

pressure
temperature
volume
moles

Answer 1

Answer: Pressure

Explanation:

The pressure is sometimes measured in different units

Answer 2

Answer:

pressure

Explanation:

The different values of R are as follows:

R = 0.0821 liter•atm/mol•K.

R = 62.3637 L•Torr/mol•K or L•mmHg/mol•K.  

Here the different units of pressure are atm, Torr and mmHg.  

The unit of volume, temperature and moles are Liter (L), Kelvin (K) and mol respectively.

When different values of Pressure are used and expressed in different units that cause a change in the value of R.
