Ideal Gas Law Mole Calculation
The table provides the pressure, volume, and temperature for a sample of a gas. Which of the following shows the correct setup for calculating the number of moles, , of the gas using the ideal gas law, ?
| Parameter | Value |
|---|---|
| Pressure | 2 atm |
| Volume | 10 L |
| Temperature | 300 K |
A
Using the ideal gas molar volume at STP (22.4 L/mol) to compute moles at 300 K, which is inappropriate for non-STP conditions.
B
Multiplying the pressure and volume without including the ideal gas constant or temperature, leading to an incorrect result.
C
Calculating moles with .
D
Adding the values of pressure, volume, and temperature together to derive the number of moles, a method that disregards the ideal gas law.
