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.

Answer:
A. An identification of the atoms in a molecule
Explanation:
The chemical formula of a compound is a representation which shows all the elements therein and the mole relationship between them expressed as subscripts.
Therefore, a chemical formula allows us to identify atoms that are within a molecule.
A molecule is a covalent compound that has discrete or separate units.
For example;
HCl represents 1 mole of hydrogen chloride molecules consisting of 1 mole of hydrogen atoms and 1 mole of chlorine atoms.
Answer:
Explanation:
1...............
CoCl₂ is an ionic compound
CF₄ is molecular
BaSO₄ is an ionic compound
NO is molecular
An ionic compound is a compound which forms between a metal and non-metal. It involves the formation of a bond between two ions of significant electronegative difference. It results from the electrostatic force of attraction between two atoms in which one has lost an electron(metal) and the other that has gained an electron(non-metal).
CoCl₂ is an ionic compound
BaSO₄ is also ionic
A molecular compound is formed as a result of covalent bonds between atoms. This is due to the fact that the two atoms have similar electronegativities and would both pull the shared electrons closely. Most molecules are usually formed this way.
CF₄ and NO are both molecular compounds
2...... The ionic compounds are the ones containing metals:
In CoCl₂ the metal is Co, cobalt
BaSO₄ has Ba
Co is a transition metal. Transition elements are known to have various oxidation states. This implies that they can form more than one type of ion. The oxidation number of Co are -1, 0, +1, +2, +3 and +4
Ba will only form one type of ion as an alkaline earth metal. It has an oxidation state of +2 only. It will only form one type of ion.
