95.3g/mole

Explanation:

To find the molar mass of substance, we sum the atomic masses of the number of atoms present.

The molar mass of  a compound is grams per mole mass of the atoms it contains.

For MgCl₂;

 Atomic mass of Mg = 24.3g/mol

                            Cl = 35.5g/mol

Molar mass = 24.3 + 2(35.5) = 95.3g/mole

A pure white crystalline compound was found to melt at 112.5-113.0oC when taken on a melting point apparatus, and on further hea
Sergeeva-Olga [200]

According to the question, the determined melting point of the compound is 112.5-113.0oC. When the solidified compound was retried, the melting point was found to be 133.6-154.5oC. This greater range higher than  112°C is caused by reusing samples leads to errors.

A pure sample is known by its sharp melting point. A pure sample does not melt over a large range. We can see this in the predetermined melting points of the pure sample(112.5-113.0oC).

However, reusing a sample introduces errors because the pure sample may become contaminated leading to a larger and higher range of melting point (133.6-154.5oC) which is far above  112°C.

The variations in the physical characteristics between different proteins are influenced by the overall amino acid compositions,
pishuonlain [190]

Answer:

Sequence

Explanation:

Physical properties of the proteins are foundation of biological function of them.

A protein molecule is made up from the long chain of the amino acids. Each amino acid is linked to its neighbor by covalent peptide bond. Thus, proteins are also called as polypeptides.

Each protein has unique sequence of the amino acids, exactly same from one molecule to next. Different proteins has its own particular sequence of amino acid. This sequence is responsible for folding and binding of the protein and also its physical characteristics.
