The formula to calculate the System Enthalpy (Hs) is:
\[ H_s = n \cdot C_p \cdot \Delta T \]
System Enthalpy is the thermodynamic quantity equivalent to the total heat content of a system. Number of Moles of Ideal Gas is the amount of gas present in moles. 1 mole of gas weighs as much as its molecular weight. Molar Specific Heat Capacity at Constant Pressure, (of a gas) is the amount of heat required to raise the temperature of 1 mol of the gas by 1 °C at the constant pressure. Temperature Difference is the measure of the hotness or the coldness of an object.
Let's assume the following values:
Using the formula:
\[ H_s = 3 \cdot 122 \cdot 400 \approx 146400 \]
The System Enthalpy is approximately 146400 Joule.
