Question

Write a program to determine the mass of oxygen gas (formula: O₂, molecular weight = 32 grams per mole) in units of grams in a container. You may assume that the user will provide the volume of the container in units of gallons, the temperature in the container in degrees Celsius, and the pressure in the container in units of atmospheres. For your test case, you may assume that the user provides 1.25 gallons for the volume of the container, 125 degrees Celsius for the temperature, and 2.5 atmospheres for the pressure in the container.

`Hey,

Note: Brother if you have any queries related the answer please do comment. I would be very happy to resolve all your queries.

#include <iostream>

using namespace std;

int main()
{
double P,v,m,M=32.0,T;
cout<<"Enter P: ";
cin>>P;
cout<<"Enter v: ";
cin>>v;
cout<<"Enter T: ";
cin>>T;
T=T+273;
double R=0.08206;
m=(P*v)*M/(R*T);
cout<<"mass is grams is "<<m<<endl;
  

return 0;
}

Kindly revert for any queries

Thanks.
