Hint: Arsenic is a chemical element signified by the symbol $As$ which have atomic number $33$ . It follows in several minerals and it is kept under the class of metalloids. It is recycled as a n-type dopant in semiconductor devices.

Arsenic is a chemical element with sign $\;As$ and atomic number $33$ . Categorized as a metalloid, arsenic is a solid at room temperature.The ordinary mass of one atom of arsenic is $74.92\;amu$ , and the mass of $1{\text{ }}mol$ of arsenic atoms is $74.92{\text{ }}grams$ .
The molar mass of Arsenic is $74.92 \cdot g \cdot mo{l^{ - 1}}$ .
The mass of $291{\text{ }}moles$ is:
$74.92 \cdot g \cdot mo{l^{ - 1}} \times 291 \cdot mol\; = \;22 \times {\text{ }}{10^3} \cdot g$
The mole is signified by the symbol mol. It is the unit of measurement for quantities in Sl units wherever Si stands for International System units. A mole of substance or particles can be defined as containing accurately $6.02214076\times 10^{23}$ particles and the particles may be atoms, ions or electrons. In summary $1{\text{ }}mol$ contains $6.02214076\times 10^{23}$ of the quantified particles and these $6.02214076\times10^{23}$ acknowledged as Avogadro's constant.

Similar to germanium, selenium, and bromine, which alike arsenic be successful the $3d$ transition series, arsenic is much less established in the group oxidation state of $+ 5$ than its upright neighbors Phosphorus and Antimony, and from now arsenic pentoxide and arsenic acid are potent oxidizers.
