Specific heat capacity

A solid of mass $0.80\,\text{kg}$ at $20^{\circ}\text{C}$ is heated at constant pressure until it reaches $50^{\circ}\text{C}$. The specific heat capacity of the solid is $900\,\text{J kg}^{-1}\,\text{K}^{-1}$. Using the definition of specific heat capacity, calculate the thermal energy supplied to the solid.
