Define a function compute_gas_volume that returns the volume of a gas given parameters pressure, temperature, and moles. Use

jeyben [28]

Question:

Define a function compute_gas_volume 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.

Answer:

This solution is implemented in C++

double compute_gas_volume(double P, double T, double n){

double V = 8.3144621 * n * T/P;

return V;

}

Explanation:

This line defines the function, along with three parameters

double compute_gas_volume(double P, double T, double n){

This calculates the volume

double V = 8.3144621 * n * T/P;

This returns the calculated volume

return V;

}

To call the function from the main, use:

cout<<compute_gas_volume(P,T,n);

Where P, T and n are double variables and they must have been initialized
