Calculating Pressure of Oxygen Gas

Consider a sealed container with a volume of 20.0 L containing oxygen gas (O₂) at a temperature of 300 K. According to the ideal gas law, the pressure of a gas can be calculated using the formula P = (nRT) / V, where P is the pressure, n is the number of moles of gas, R is the ideal gas constant (0.0821 L·atm/(K·mol)), T is the temperature in Kelvin, and V is the volume in liters.

In this scenario, if the number of moles of oxygen gas in the container is 1.5 moles, what will be the pressure of the gas inside the container?
