Part -1:
1. An EMT needs 2.0 liters of a 0.90 M NaCl solution for an IV bag. How would he runkt thiq solution from a 4.00 M stock solution'? How would he make this from solid NaCl?
2. How would a nurse make 10 milliliters of a lidocailic stock solution diluted to 1/10 of its concentration?
Part -2:
1. Rarely do chemists reach 100% recovery from a reaction. especially with a series of reactions. Using this lab as an example, give one reason why a percent recovery could be less than 100% and one reason why a percent recovery could be more than 100%. (Since you are given time to prepare for this calculation, answers with calculation and procedure mistakes are NOT acceptable.)
Use the following equations for the next questions for the synthesis of ethanol (C2H60). Ethanol (the alcohol found in liquor and in modem gasoline) is fermented from the sugar glucose (C6F11206) anaerobically in a two-step process, making pyruvate (C3H603) first.
a. C6H12O6 -> 2C3H6O3 b. C3H6O3 C2H6O + CO2
2. What are the formula weights of glucose (C6H12O6) and ethanol (C2H6O)?
3. How many moles of glucose are there in a 1,945.3 g sample of glucose? How many moles of pyruvate (C3H603) could you make from this many moles of glucose?
4. How many moles of ethanol (C2H60) are there in 4.987 moles of pyruvate (C3H6O3)? How many grams of ethanol can you make from this many moles of ethanol?
