Answer:
17.2 minutes is the value of the turnover number.
Explanation:
Using Michaelis-Menten equation:
![V = V_{max}\times \frac{[S]}{ (Km + [S])}](https://tex.z-dn.net/?f=V%20%3D%20V_%7Bmax%7D%5Ctimes%20%5Cfrac%7B%5BS%5D%7D%7B%20%28Km%20%2B%20%5BS%5D%29%7D)
Where :
= max rate velocity
[S] = substrate concentration
= Michaelis-Menten constant
V = reaction rate
= catalytic rate constant
= initial enzyme concentration
We have :
is the rate is obtained when all enzyme is bonded to the substrate. is termed as the turnover number.
17.2 minutes is the value of the turnover number.

Molality of the solution is defined as the number of moles of a substance dissolved divided by the mass of the solvent:
Molality = number of moles / solvent mass
From the concentration of 39% (by mass) of HCl in water, we construct the following reasoning:
in 100 g solution we have 39 g hydrochloric acid (HCl)
number of moles = mass / molecular weight
number of moles of HCl = 39 / 36.5 = 1.07 moles
solvent (water) mass = solution mass - hydrochloric acid mass
solvent (water) mass = 100 - 39 = 61 g
Now we can determine the molality:
molality = 1.07 moles / 61 g = 0.018
Answer:
63 mL
Explanation:
To find the amount of mililiters in an amount of liters, we must multiply by the amount of liters by 1000.
0.063 L × 1000 = 63 mL
Elements and compounds are both examples of pure substances. Compounds are substances that are made up of more than one type of atom. Elements are the simplest substances made up of only one type of atom. i hope that helps:)
