Universal Gas Constant

The universal gas constant is a physical constant that relates the properties of a gas to the amount, temperature, and pressure of the gas. It is denoted by the symbol R and has the value:

R = 8.314 J/(mol·K) (in SI units)

However, the universal gas constant can also be expressed in other units, such as kgf·m/(mol·K), which is the unit used in this question.

Calculation

To convert the universal gas constant from J/(mol·K) to kgf·m/(mol·K), we can use the following conversion factors:

1 J = 0.101971621 kgf·m
1 kgf = 9.80665 N

Substituting these values, we get:

R = 8.314 J/(mol·K)
R = 8.314 × 0.101971621 kgf·m/(mol·K)
R = 0.846736 kgf·m/(mol·K)

Rounded to three significant figures, this gives us the answer of 0.848 kgf·m/(mol·K), which is option C.

Conclusion

The universal gas constant relates the properties of a gas to the amount, temperature, and pressure of the gas. It is usually expressed in SI units of J/(mol·K), but can also be expressed in other units such as kgf·m/(mol·K). To convert from J/(mol·K) to kgf·m/(mol·K), we need to use conversion factors for joules and kilograms force, as shown above.
