The assumptions made in calculating the Michaelis-Menten Equation include
Sauron [17]

Answer:

c) that the formation and decomposition of ES is the same for a period of time

Explanation:

Michaelis-Menten equation :

This model  explain the approach to enzyme kinetics.The Equation shows how a Free enzyme E and Product P is formed depicting by Following equation.

                       E+S⇌ES→E+P

Left side represents

E =enzyme

S=substrate

ES=enzyme-substrate complex

Right side

E= Free enzyme

P= product

c) that the formation and decomposition of ES is the same for a period of time

KCl is an ionic salt with a formula weight of 74.54 g/mole. A 1.417 M (mole/liter) KCl solution has a density of 1064.5 grams/li
xenn [34]

Answer:

Mass of the salt:  105.6g of KCl.

Mass water: 958.9g of water.

Molality: 1.478m.

Explanation:

<em>Mass of the salt:</em>

In 1L, there are 1.417 moles. In grams:

1.417 moles KCl * (74.54g / mol) = 105.6g of KCl

<em>Mass of the water:</em>

We can determine the mass of solution (Mass of water + mass KCl) by multiplication of the voluome (1L and density 1064.5g/L), thus:

1L * (1064.5g / L) = 1064.5g - Mass solution.

Mass water = 1064.5g - 105.6g = 958.9g of water

<em>Molality:</em>

Moles KCl = 1.417 moles KCl.

kg Water = 958.9g = 0.9589kg.

Molality = 1.417mol / 0.9589kg = 1.478m
