//Given Data
temperature=300; //Temperature of the water vapour (Unit: Kelvin)
volume=1; //Volume of the water vapour(Unit : m^3)
molecular_weight_water=18; //Molecular weight of the water (Unit: g/mol)
r=8.3; //Gas constant (Unit: J/mol-K)
relative_humidity=50/100; //Relative humidity of the air (Unit: percentage)
pressure=3.6*10^3; //Pressure of the water vapour (Unit: Pascal)
//Formula: PV=nRT
//Calculation
mass_of_vapour=molecular_weight_water*pressure*volume/(r*temperature); //Calculation of mass of vapour (Unit: gram)
amount_vapour=relative_humidity*mass_of_vapour; //Calculation of vapour after considering relative humidity (Unit : gram)
disp(amount_vapour,"As the relative humidity is 50% , the amount of vapour present in 1 m^3 is (Unit : gram)");
