The value of gas constant 'R' is__________________?
Correct answer: C. Both A. and B
- A. 1.987 cal/gm mole °K
- B. 1.987 BTU/lb. mole °R
- C. Both A. and B
- D. Neither A. nor B
Explanation
The universal gas constant is 1.987 cal/(g mol·K) and approximately 1.987 BTU/(lb mol·°R), so both listed values represent the same constant in different unit systems.
