Define a function ComputeGasVolume that returns the volume of a gas given parameters pressure, temperature, and moles. Use the gas equation PV = nRT, where P is pressure in Pascals, V is volume in cubic meters, n is number of moles, R is the gas constant 8.3144621 ( J / (mol*K)), and T is temperature in Kelvin. Sample program:#include const double GAS_CONST = 8.3144621;int main(void) { double gasPressure = 0.0; double gasMoles = 0.0; double gasTemperature = 0.0; double gasVolume = 0.0; gasPressure = 100; gasMoles = 1 ; gasTemperature = 273; gasVolume = ComputeGasVolume(gasPressure, gasTemperature, gasMoles); printf("Gas volume: %lf m^3\n", gasVolume); return 0;}
