The value of n for the given empirical formula and molecular mass is 5.00.

<u>Given the following data:</u>

Empirical formula = $C_3H_5$

Molecular mass = 205. 4 g/mol.

<u>Scientific data:</u>

Molar mass of carbon (C) = 12 g/mol.

Molar mass of hydrogen (H) = 1 g/mol.

To determine the value of n for the given empirical formula and molecular mass:

<h3>How to calculate molecular formula.</h3>

First of all, we would determine the gram-mass of the chemical compound as follows:

$C_3H_5 = (12 \times 3)+(1 \times 5)$

C_3H_5 = 36+5

C_3H_5 = 41 g/mol.

<u>For the </u><u>molecular formula</u><u>:</u>

(CH)n = 205.4

41n = 205.4

n =\frac{205.4}{41]

n = 5.00

In anticipation of receiving a fertilized ovum, the lining of the uterine wall

Mariulka [41]

Every month, the lining of the uterus becomes thicker in preparation for an egg that has been fertilized to place itself there. In the event that this transpires, hormones originating from the reproductive organs will stabilize the vascular tissue of the endometrium, which in turn will offer a setting for the embryo to grow in.

This is further explained below.

<h3>What is the uterine wall?</h3>

Generally, The uterine lining grows every month in anticipation of the implantation of a fertilized ovum. When this happens, the endometrium's vascular tissue is stabilized by hormones from the reproductive organs, providing an environment for the growing fetus.

In conclusion, There are three distinct layers of muscle tissue that compose the uterine wall. The muscle fibers are intertwined with the connective tissue of blood vessels, elastic fibers, and collagen fibers, and they may run in either of three directions: longitudinally, circularly, and obliquely. As the baby grows within the uterus, this thick muscular wall begins to stretch out and eventually becomes much thinner.
