# Approximate Calculations

## Approximate Calculations

calculations in which the data and the result—or at least the result—are numbers that only approximately represent the true values of the corresponding quantities. Approximate calculations are performed in the numerical solution of problems and are a result of inaccuracies inherent in the formulation of the problem and in the methods of the problem’s solution. The general rules and the theory of methods of approximate calculation are commonly referred to as numerical methods.

The energetics of Equation 1 are [DELTA]H[degrees](1100 K) = + 75 kJ [mol.sup.-1], [DELTA]G[degrees](1100 K) = -14 kJ [mol.sup.-1], using approximate calculations. In the CarbonSaver process, the energy to liberate elemental hydrogen is supplied by 100 kilowatts of microwave energy (requiring electricity), which can be considered to contribute to the internal energy of the system.
