What is the number for pressure constant?
The number for pressure constant is usually denoted as (R) and has a typical value of 0.0821 L·atm/mol·K. This constant is commonly used in the ideal gas law equation, PV = nRT, where (P) is pressure, (V) is volume, (n) is the number of moles, (T) is temperature, and (R) is the ideal gas constant.
