Question

What does the ideal gas law allow a scientist to calculate that the other gas laws do not?

Answer 1

The number of moles of the gas can be calculated from the ideal gas law, as well as the gas constant.

Explanation:

Only the ideal gas law includes a variable for moles and the gas constant.

The equation for the ideal gas law is `PV=nRT`, where `n` is moles, and `R` is the gas constant.

To solve for moles, rearrange the equation to `n=(PV)/(RT)`.

To solve for the gas constant, rearrange the equation to `R=(PV)/(nT)`.
