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.
We produce formaldehyde for medicinal purposes and synthesizing polyester.
Formaldehyde is a compound that is required in about 1.5 ounces in quantity as a normal part of our metabolism.
Also formaldehyde is used as a catalyst in the formation for the synthesis of many polyesters.
Formaldehyde also has many uses such as fungicide, germicide, disinfectant and as a preservative in mortuaries as well as important chemical in medical Laboratories.
In everyday items press fabric paints coating and paper base products also includes formaldehyde.

Answer:
1.602 L (or) 1602 mL
Explanation:
Molarity is the amount of solute dissolved per unit volume of solution. It is expressed as,
Molarity = Moles / Volume of Solution ----- (1)
Rearranging above equation for volume,
Volume of solution = Moles / Molarity -------(2)
Data Given;
Molarity = 0.00813 mol.L⁻¹
Mass = 1.55 g
First calculate Moles for given mass as,
Moles = Mass / M.mass
Moles = 1.55 g / 119.002 g.mol⁻¹
Moles = 0.0130 mol
Now, putting value of Moles and Molarity in eq. 2,
Volume of solution = 0.0130 mol / 0.00813 mol.L⁻¹
Volume of solution = 1.60 L
or,
Volume of solution = 1602 mL
