the atmosphere. You know the initial volume, temperature, and air pressure. What informa-tion will you need to predict the volume when it reaches its final altitude? Which law would you use to calculate this volume? You would need to know the final temperature and final pressure to calculate the final volume. Use the combined gas law. 17. Since the volume is constant but the pressure and temperature are changing, this is an example of Gay-Lussac's Law The initial pressure was 1.58 atm. (You used the wrong formula for Gay-Lussac's Law.)
Water dilution Grapes with too much sugar means a lot of alcohol will be produced and this can cause problems with the primary and secondary fermentations. High alcohol level is becoming inhibitor for most yeast strains and malolactic bacteria and actually kills them, which can cause a sluggish or stuck fermentation.

(Note: If the initial pressure value is changed, then a new value of moles will be calculated to be consistent with the initial volume and temperature specified above. If you wish to restrict the number of moles to your supplied value, then enter that value plus values for initial volume and temperature - the required pressure will be calculated.

Record the final volume of NaOH in the data section. You do not need to add more NaOH to the buret between trials. Use the final volume from the first trial as the initial volume for the second trial. Use the volume of NaOH and grams of KHP to calculate the molarity of the NaOH solution. (If you need help, see the equations in your prelab).
These spaces are described mathematically as volume(s) of distribution. In the simplest of terms, a drug's volume of distribution is that volume of bodily fluid into which a drug dose is dissolved. Therefore, if we know the dose that was given, and we can measure the serum level (concentration), then we can calculate a volume:

we use the initial condition C(0) = 1 2. This gives us K = 200 3 2 = 100(2002). So the concentration of the solution in the tank at any time t (before the tank over ows) is C(t) = 1 100(2002)(200 + t) 3: Since the amount of salt in lbs (call this value A(t)) is just the concentration of the solution times its volume, we get A(t) = (200 + t)C(t) = (200 + t)
