Calculate the heat required to raise 50.0 kg of solid sodium carbonate (Na,COg) from 10.0 °C to 59.0 °C at 1 atm using the following two methods. A. Use the true heat capacity of Na,CO3, which is 1.14 kJ/(kg °C). Use a heat capacity estimated by Kopp's rule, and calculate the percentage error from the true value. B. Use Kopps rule to estimate the heat capacity of NaCO3. C. Use the Kopp's rule heat capacity to estimate the required heat. What is the percentage error of the Kopp's-rule estimate from the true value? (positive number)
