In the ideal gas equation PV=nRT, what does 'n' represent?
Correct Answer: Number of moles of the gas
- Step 1: Understand the ideal gas equation, which is PV = nRT.
- Step 2: Identify each variable in the equation: P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature.
- Step 3: Focus on the variable 'n'.
- Step 4: Recognize that 'n' specifically refers to the amount of gas present, measured in moles.
- Step 5: Conclude that 'n' tells us how many moles of gas are in the system.
