If an endothermic process absorbs 256j how many kilocalories are absorbed
Finger [1]
There are several units for expressing energy, Most common are joules and kilocalories.

The conversion factor of joule to kilocalories is 
 1 kilo calorie  = 4184 J
∴ x kilo calorie = 256 J

x = \frac{256}{4184} = 0.0611 kilo calories

Thus, 256 J = 0.0611 kilocalories
