Answer:

C M (change in T) = heat absorbed thermal equation for heat gained

C = 418.4 J / (2 kg * 50 deg K) = 4.184 J / kg * deg K specific heat

Note: 1 gm =.001 kg

So C = .004184J / gm * deg K

Also, 1 J = .239 cal so in conventional terms

C = .001 cal / gm deg K (very low, water would be 1 cal / gm deg C
