2. STP = standard temperature and pressure (1.00 atm, 273 K); R = gas constant (0.0821 Lxatm/molxK)
3. Rearrange the equation above to solve for n (number of moles). n = PV/RT
n = (1.00 atm x 4.00 L)/(0.0821 Lxatm/molxK x 273 K) = 0.178 moles
0.178 moles of CO2
The number of moles will be 0.178 moles. It can be calculated by ideal gas law.
What is ideal gas law?
The ideal gas law gave the relationship between pressure, volume as well as temperature. It can be expressed as:
Where, P is pressure, V is volume and T is temperature.
Calculation of number of moles by using ideal gas law.
Put the value of given data in above ideal gas law formula.
n = PV / RT
n = (1 atom × 4 L)/ (0.0821 × 273 K
n = 0.178 moles.
Therefore, the number of moles will be 0.178 moles.
