Question

which of the following represent the value of gas constant R in joule per degree per mole
a. 1.987
b. 8.31×10 raise to power 7
c. 0.082
d. 8.314​

Answer 1

Answer:

PLEASE MARK ME AS BRAINLIEST

Gas constant is 8. 31×10^7

So option is b

Answer 2

Answer:

Option D- R=8.314J/mole-per degree.

Explanation:

In the ideal gas equation,

PV=nRT                                                

R is the universal gas constant which is independent of the values of pressure, volume, temperature and nature of gas and remains constant in all conditions.

Rather it's value depends on the unit of pressure, volume, temperature.

Standard value of R is as,

R=8.314J/mole-kelvin

Since change in temeperature in kelvin and degree celcius is same in magnitude so value of R also remains the same.

Hence, R=8.314J/mole-per degree
