Worksheet cal Show one calculation for the heat capacity of the calorimeter, C. Report the value in J K-¹, to 2 dp. Do not use scientific notation. This is not necessarily the correct number of SF but will prevent round- ing errors in subsequent calculations. 9abs = CAT+mcAT Show the calculation for the heat absorbed by the calorimeter and the NaCl solution in Part 2. 9abs = CAT+mcAT
