The ideal gas constant R has a value of approximately:

A 8314 J/(mol·K)

B 8.314 J/(mol·K) or 1.987 cal/(mol·K)

C 0.08206 J/(mol·K)

D 273 J/(mol·K)

✓ Correct Answer: Option B

R = 8.314 J/(mol·K) = 0.08206 L·atm/(mol·K) = 1.987 cal/(mol·K). Universal gas constant.

💡 Why is B) the correct answer?

The correct answer to the question "The ideal gas constant R has a value of approximately:" is Option B: 8.314 J/(mol·K) or 1.987 cal/(mol·K).

The other options — A) 8314 J/(mol·K), C) 0.08206 J/(mol·K), D) 273 J/(mol·K) — are incorrect for this FE Exam Prep question. As explained above: R = 8.314 J/(mol·K) = 0.08206 L·atm/(mol·K) = 1.987 cal/(mol·K). Universal gas constant.
