Every valentine’s day, CVS sells chocolate-covered cherries. The chocolate-covered cherries are like a mini cake with a cherry inside. The cake comprises a combination of sucrose (powder sugar), butter, cherry juice, and an enzyme (invertase). While stored at 5.00C, the sucrose hydrolyzes to produce glucose and fructose. The mixture of the glucose and fructose is a liquid called invert sugar. Below you will find the concentration of sucrose in the cake as a function of time. For the cherries to be edible, more than 80% of the sucrose must be hydrolyzed. Before you start to answer the question, create a data table that comprises sucrose concentration in units of moles per liter. Time (hours) Sucrose Concentration (g/cm3) 0 0.844 24 0.681 48 0.550 96 0.357 192 0.153 Convert your sucrose concentration to molarity below. Round to the proper number of significant figures, based on your given information. Sucrose conc. (g/cm3) Sucrose conc. (Molarity) 0.844 0.681 0.550 0.357 0.153 1. With the data above, determine how long it will take (in hours) for 83.7% of the sucrose to be converted into glucose and fructose. (answer with the proper number of significant figures) 2. What would happen if the invertase was not included in the recipe?
