The correct answer is B. Gallium arsenide

Explanation:

The abbreviation or formula GaAs refers to the chemical compound gallium arsenide, that as indicated by its name contains gallium, which is a metal, and arsenic, which is a metalloid. This compound is more commonly used as part of the manufacturing processes of multiple devices such as microwaves or computers because this is a semiconducting material, and due to this, it is ideal for creating circuits. According to this, the compound GaAs refers to Gallium arsenide.

I found a similar question online which will help me answer your incomplete question. To make it easier, show all the elements of the compound given. It is shown in the second picture attached.

a.) The formula for unsaturation number is shown in the 3rd picture attached. Following this,
n = 8
m = 2(8) + 2 + 0 + 0 - 0 = 18
Thus,
x = Unsaturation number = (18 - 8)/2 = 5
<em>The unsaturation number is 5.</em>

b.) The molar mass of C is 12.01 g/mol; H is 1 g/mol; O is 16 g/mol. So, the molecular weight is:
Molecular weight = 12.01(8) + 8(1) + 2(16) = 136.08 g/mol
<em>The molecular weight of the ester is 136.08 g/mol.</em>

The average atomic mass of chromium to 3 decimal points is 52. 055 g. mol.

<h3>What is the average atomic mass?</h3>

"The weighted average mass of the atoms in a naturally occurring sample of an element is the average atomic mass, also known as atomic weight."

Given the different isotopes of chromium.

The four isotopes of chromium are cr-50, cr-52, cr-53 cr-54.

The average atomic mass will be

Let us take the weighted average of your isotopes:

50 × 0.0434 + 52 × 0.8379 + 53 × 0.095 + 54 × 0.0237 = 52. 055 g.

Thus, the average atomic mass of chromium is 52. 055 g.
