SUMMARY
The mass of glycerin can be accurately calculated using the formula Q = C*M*(T2-T1), where Q represents the energy input, C is the specific heat capacity, and T2-T1 is the temperature change. In this discussion, the specific heat capacity of glycerin is confirmed to be 2400 J/kg·K. Using this value, the calculated mass of glycerin is approximately 0.545 kg when 5.50 x 103 J of energy causes a 4.20°C temperature rise. The discrepancy in results arises from the incorrect use of units for specific heat capacity.
