Question

In the ideal gas laws equation, PV=nRT, the variable n stands for?

1) a constant
2) the number of atoms
3) the number of moles
4) the principal quantum number

Answer 1

In the ideal gas law equation PV = nRT, the variable 'n' represents the number of moles of the gas. The correct option is 3.

Step-by-step explanation:

In the ideal gas law equation, which is represented as PV = nRT, the variable n stands for the number of moles of the gas. T

he other variables in the equation are P (pressure), V (volume), T (temperature in Kelvin), and R (the ideal gas constant). This law relates the four state variables of a gas under a particular set of conditions and can be used to calculate the value of one of these variables if the others are known. It's also the foundation for understanding how gases behave under different conditions.

Hence, Option 3 is correct.
