hey everyone i have a conceptual question mostly, but here is the problem, and I will show you what i have so far.
problem: If we start with 325 g of water at 30.0 degrees celcius, how much heat must we add to convert all the liquid into vapor at 100 degrees c.
I know that we have to do the phase transition: 325 g(1mol/18.02g)(40.7kj/mol)=734.04kJ.
would i be done there? or do i have to also do q=mc(change in temp) 325g(4.184j/gc)(100-30)=95.1kJ to heat the water and add 734.04kj+95.1kJ. please help. thanks
