1. Ideal gas law: PV = nRT

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:

PV =nRT

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.
