tricky specific heat problem

[Sarahisme]

hey i've got a bit of a tricky (i think it is anyway ) specific heat problem, and i just wanted to check that i'd got it right.

 

so if anyone has a couple of mins free, could they please check my answer?

 

Thanks

my answer is : [math]c_m = 450 \frac{J}{kg.K} [/math]

The numerical one is correct but I'm not sure about the unit.

[Sarahisme]

ok, cool, thanks! whats wrong with the units? their standard specific heat unit arnt they? (they use the same units for specific heat in the question)

Looks good. The units are fine, since they are the same as the given specific heats.
