A.)
300 ml * 8 = 2.4 gallons a day.
now time to see how much a year..
2.4 * 365 = 876 liters
B.)
one liter = 2.2 pounds
876 x 2.2 = 1927.2 pounds
Answers:
<u>A.) 2.4 * 365 = 876 liters</u>
<u>B.) 876 x 2.2 = 1927.2 pounds</u>
The optimal pH is 6.9. The pancreatic amylase is a hydrolase secreted by pancreas and will go into the alimentary canal. The working environment has a pH of 6.9. So the optimal pH for the enzyme needs to be 6.9.
229.25 mL of isopropyl alcohol
425.75 mL of water
Explanation:
Knowing that the solution have a 35.0 % (v/v) isopropyl alcohol in water, we can calculate the volume of each component as following.
volume of isopropyl alcohol = (35/100) × solution volume
volume of isopropyl alcohol = 0.35 × 655 mL = 229.25 mL
Now, knowing the volume of isopropyl alcohol we can determine the volume of water.
volume of the solution = volume of isopropyl alcohol + volume of water
volume of water = volume of the solution - volume of isopropyl alcohol
volume of water = 655 mL - 229.25 mL = 425.75 mL
