A 125-mL sample of an aqueous solution of the protein ovalbumin from chicken egg white contains 1.31 g of the dissolved protein
Stella [2.4K]

The molar mass of the protein is 45095 g/mol.

The mass of a sample of a chemical compound divided by the quantity, or number of moles in the sample, measured in moles, is known as the molar mass of that compound.

The expression of molar mass of protein is

M₂ = (W₂/P) (RT/V)

Given;

W₂ = 1.31g

P = 4.32 torr = 5.75 X 10⁻³ bar

R = 0.083 Lbar/mol/K

T = 25°C = 298.15 K

V = 125 ml = 0.125 L

Putting all the values in the above formula

M₂= (1.31 g/5.75 X 10⁻³ bar) X (0.083 Lbar/mol/K X 2)/0.125 L)

M₂ = 45095 g/mol

Thus, the molar mass of the protein is 45095 g/mol.

What happens to the atomic radius when an elctron is lost​
Daniel [21]

Answer:

It decreases.

Explanation:

Due to changes in the Coulombic force, the protons within the nucleus of the ion have a much easier time pulling at one fewer electrons. This way, the electrons are pulled closer to the center, causing the radius to decrease.
