Homework Help: Physics

A steam engine's boiler completely converts 155 kg of water to steam. This process involves the transfer of 3.5 x 10^8 J by heat. If steam escaping a safety valve does 1.76 x 10^8 J of work against the outside atmosphere, what is the net internal energy of the water-steam system?

Do I need to use the mass and specific heat of water to find Q, or am I making this more complicated than it is?
