Answer:
Q = mass in grams x delta T x 4.18 J/g C
this would be the same for celius units as kelvins as the units are the same size
2825 J = mass x 25C x 4.18 J/gC
mass = 2825J/ (25C x 4.18 J/gC)= 27.1g water
slide rule accuracy as I had no calculator- it is refreshing to remember how a really well crafted bamboo slide rule works
