6.19.1: Function to compute gas volume. 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. All parameter types and the return type are double.

R = 8.3144621

def ComputeGasVolume(pressure, temperature, n):

   volume_of_gas = (n * R * temperature) / pressure

   return volume_of_gas

Explanation:

*The code is in Python.

- Initialize the constant value of R

- Create a function called ComputeGasVolume() that takes three parameters: pressure, temperature, and n

- Calculate the volume of the gas using given formula, PV = nRT → V = nRT/P

- Return the volume of the gas

See explaination

Explanation:

import java.util.Scanner;

public class GasVolume {

final static double GAS_CONST = 8.3144621;

public static double computeGasVolume(double pressure,double temperature, double moles)

{

return moles*GAS_CONST*temperature/pressure;

}

public static void main(String[] args) {

Scanner scnr = new Scanner(System.in);

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);

System.out.println("Gas volume: " + gasVolume + " m^3");

return;

}

}
