Question

Help please

Which of the following are correct values for the ideal gas law constant R? Select all that apply.

8.314 L-atm/mol-K
8.314 kPa-L/mol-K
0.0821 kPa-L/mol-K
0.0821 L-atm/mol-K

Answer 1

0.0821 L-atm/mol-K
8.314 kPa-L/mol-K

Answer 2

Answer : The correct options are, (2) 8.314 kPa-L/mol-K and (4) 0.0821 L-atm/mol-K

Explanation :

As we know that the 'R' is the gas constant in the ideal gas law.

There are different values of gas constant 'R'. The values are,

`8.314JK^(-1)mole^(-1)\\\\0.0821L\text{ atm }K^(-1)mole^(-1)\\\\0.08314L\text{ bar }K^(-1)mole^(-1)\\\\8.314K\text{ Pa }LK^(-1)mole^(-1)\\\\2calK^(-1)mole^(-1)`

Hence, the correct options are, (2)
`8.314K\text{ Pa }LK^(-1)mole^(-1)` and (4)
`0.0821L\text{ atm }K^(-1)mole^(-1)`
