The value of the gas-law constant 'R' is 1.987 ?
Correct answer: D. Both B. & C.
- A. kcal/kg-mole.°C
- B. Btu/lb-mole.°R
- C. kcal/kg-mole.°K
- D. Both B. & C.
Explanation
The universal gas constant is 1.987 kcal/(kg-mol·K) and equivalently about 1.987 Btu/(lb-mol·°R). Thus, both units in options B and C represent the same value of R.
