62.36
Verified step by step guidance1
Identify the given values of the gas constant, R, in different units: 8.314 J/(mol·K), 1.987 cal/(mol·K), and 62.36 L·torr/(mol·K).
Recognize that the problem asks for the value of R in units of L·atm/(mol·K).
Convert the value of R from J/(mol·K) to L·atm/(mol·K) using the conversion factor: 1 J = 0.00986923 L·atm.
Perform the conversion: Multiply 8.314 J/(mol·K) by 0.00986923 L·atm/J to obtain the value in L·atm/(mol·K).
Ensure the final value is reported with at least three significant figures, as required by the problem.
