From the experiment, it was determined that pure urea had a melting point of 131.2 ˚C -136.6 ˚C which falls within range of the normal melting temperature of pure urea, meaning that error occurred. Trans-cinnamic acids melting point was determined to be 133.4 ˚C -135 ˚C, which falls out of the normal melting tempature by 0.4 ˚C meaning that error must have occurred in that section of the experiment. In the lab another three samples were analyzed using different ratios of urea and trans-cinnamic acid, these mixtures all were found to have different melting point values. The sample that contained 90% Urea and 10% trans-cinnamic acid had a melting point range of 115.4 ˚C -133.4 ˚C, this value is lower than both the pure urea and pure trans-cinnamic acid. The mixture that was 50% Urea, 50% trans-cinnamic acid had the lowest melting point in the experiment. The value for the 1:1 substance was found to be between 95.8 ˚C -98.5 ˚C. The substance that was 10 % urea, 90% trans-cinnamic acid had a melting temperature of 126.7 ˚C -133.3 ˚C, making it lower than both pure
