Question

The value of the universal gas constant R is ______.

Options

• 8.31 J K⁻¹ mol⁻¹

• 6.022 × 10²³ J K⁻¹ mol⁻¹

• 1.38 × 10⁻²³ J K⁻¹

• 3.14 J K⁻¹ mol⁻¹

Answer 1

The value of the universal gas constant R is 8.31 J K⁻¹ mol⁻¹.

Explanation:

The source clearly states that R = 8.31 J K⁻¹ mol⁻¹, and it is the same for all ideal gases.
