$$c = \frac{Q}{m\Delta T}$$
where:
* c is the specific heat capacity in J/g°C
* Q is the heat absorbed in J
* m is the mass of the sample in g
* ΔT is the temperature change in °C
In this case, we have:
$$c = \frac{202.7 J}{0.994g \cdot \Delta T}$$
We don't know the temperature change, so we can't calculate the specific heat capacity. However, we can say that the specific heat capacity is the amount of heat required to raise the temperature of 1 gram of the crystal by 1 degree Celsius.
