Social Sciencewhen drawing melting point composition diagram for a mixture of something such as cinnamic acid and urea comparing melting point vs composition for organic chemistry, if i have three different compositions (1:4, 4:1,1:1) should i have 3 different graphs or would this all be on the same graph?and how do i convert grams to moles for example for composition 1:4 my data was 0.8003 g : 3.1917 g?

Expert Answer
The melting point composition diagram for mixture cinnamic acid and urea depicts the comparison between melting point of mixture and the composition of the mixture. This means that this diagram is 2 dimensional graph of temperature and composition of the mixture.
The y axis of the diagram will represent temperature and the x axis of the diagram will represent composition. In the three different compositions say, 1:4 mixture contains 100% cinnamic acid, the 1:1 composition contains 50% cinnamic acid and the 4:1 composition contains 100% urea. These three different compositions can be in Y axis of a same graph which shows the plot of different compositions with respect to different melting points.
Therefore, the Mixtures with three different compositions can be depicted in a same graph and it does not require three different graphs.
