In biological systems, enzymes are used to accelerate the rates of certain biological reactions. Glucoamylase is an enzyme that aids in the conversion of starch to glucose (a sugar that cells use for energy). Experiments show that 1 μg mol of glucoamylase in a 4% starch solution results in a production rate of glucose of 0.6 μg mol/(mL)(min). Determine the production rate of glucose for this system in units of lb mol/(ft3)(day). A. 0.0015 lb mol/(ft3)(day) B. 0.0315 lb mol/(ft3)(day) C. 0.0539 lb mol/(ft3)(day) D. 0.3569 lb mol/(ft3)(day)
When concentrated nitric is sold, the label contains no mention of the molarity of the acid. Instead, the label normally lists the concentration of nitric acid as a wt/wt percent and gives the specific gravity of the solution. If the solution is 68.0 (wt/wt %) and nitric acid and has a specific gravity of 1.41 kg/L, calculate the molarity of 68.0 % concentrated nitric acid. FW HNO3=63.01g/mol
Since the pandemic has hit, more people are growing their own gardens and processing the fruits of their work. One thing that is flying off the shelves are spices for canning, such as alum. From this lab, you have seen how easy it is to prepare an alum, and the ingredients to make this are not difficult to obtain. You are going to make a batch of pickles and the recipe requires 6.05g of alum for each quart jar of pickles and you plan on making 50 jar of pickles. The % yield of making alum is only 84.4%. a. What is the actual yield of alum that you need to prepare to make your pickles? b. What is the theoretical yield of alum required to prepare the pickles? c. What mass of aluminum do you need to start with to make the required amount of alum for the preparation of the pickles?
