1. heat=mass*c*(tf-ti)
steps? You know heat, mass, ti. The only issue is the specific heat of water UNITS. YOu need c in kJ/kgC

2. mass of water= 367,000 x specific heat (24.8?) x Tf (how do i find this? what part of the question tells me?)

3. Lord:
mass water=45kg
heat=367kJ
c= 4.17kJ/kgC
Ti=24.8C

367kJ=45kg*4.17kJ/kgC*(Tf-20)

Tf-20=367/(45*4.17)
Tf=367/(45*4.17) +20
