1.72 mol of LiCl in 37.5 L of solution
givi [52]
<h3>Answer:</h3>

Molarity is 0.046 M

<h3>Explanation:</h3>

We are given;

1.72 mol of LiCl in 37.5 L of solution

We will take the question to be; calculate the molarity of LiCl

Therefore,

we can start by defining molarity as the concentration of a solution in moles per liter.

Molarity of a solution is calculated by dividing the number of moles of solute by the volume of solution.

Molarity = Moles of solute ÷ Volume of the solution

Thus, in this case;

Molarity of LiCl = Moles of LiCl ÷ Volume of the solution

                          = 1.72 moles ÷ 37.5 L

                          = 0.0459 M

                         = 0.046 M

Therefore, the molarity of LiCl solution is 0.046 M

SVEN [57.7K]
Therefore carbohydrates are covalent compounds. Since electrons or more specifically valence electrons from their respective atoms are shared to form chemical bonds and acquire greater chemical stability from the bonds, this is present through out this biological macromolecule and is thus covalent.

What is the symbol (including the atomic number, mass number, and element symbol) for the nitrogen isotope with 8 neutrons? Expr
Doss [256]

Answer: The isotope is represented as _7^{15}\textrm{N}

Explanation:

General representation of an element is given as:_Z^A\textrm{X}

where,

Z represents Atomic number

A represents Mass number

X represents the symbol of an element

Atomic number is defined as the number of protons or number of electrons that are present in an atom.

Atomic number = Number of electrons = Number of protons  = 7 (for nitrogen)

Mass number is defined as the sum of number of protons and neutrons that are present in an atom.

Mass number = Number of protons + Number of neutrons = 7+8 = 15

Thus the isotope is represented as _7^{15}\textrm{N}
