Please help with thermodynamics question (air conditioning)? mass of water vapor in air?

Posted on 2016-04-12 15:09:00 in Engineering by JOHN FAL

Air at 1 atm, 20 degrees c, and 70 percent relative humidity is first heated to 30 degrees then humidified by introducing water vapor. the air leaves the humidifying section at 35 degrees and 80 percent relative humidity. determine the amount of steam added to the air. 

I don t know how to solve this. could I use ideal gas law and find the mass of vapor before and after humidifying then calculate the difference?
