Question

2. 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.

c language

Answer 1

#include <stdio.h>

int main()
{
double o=32,r=0.0821,v,p,t,n,m;
printf("Enter the pressure of container: ");
scanf("%lf",&p); //Taking pressure from user
printf("Enter the volume of container: ");
scanf("%lf",&v); //Taking volume from user
printf("Enter the temperature of the container: ");
scanf("%lf",&t); //Taking temperature from user
t = t + 273;
m = (p*v)*o/(r*t); //Calculating the mass
printf("The mass of oxygen gas in the conatiner is: %lf",m); //Printing the ans
  

return 0;
}
