Question

How many atoms of sulfur are in $2.4$ moles of sulphur?

Answer 1

Number of atoms that is currently in one mole of elements is the Avogadro's number. Avogadro's number $6.023 \times {\text{ }}{10^{23}}mo{l^{ - 1}}$. it is signified by the symbol ${N_A}$. sulphur's molar mass is equivalent to $32{\text{ }}g/mole$.

Complete step by step answer:
The whole thing present in this universe is made up of atoms. The mass of an atom cannot be measured really owing to its very small size. So a virtual term is used for it called relative atomic mass. It leftovers based on the mass of $1$ carbon- $12$ atom. It was approved internationally in $1961$ and afforded to it.
Mole is the amount of substance that comprehends the atoms, molecules or additional particles in a thing equal to the atoms present in $12g$ of $12$ isotope. It describes the basis of physical chemistry and so its number is called Avogadro's number which is similar to $6.023 \times 10^{23}$ things. It is signified by the symbol ${N_A}$.
Some standard terms second hand in mole concept are
gram atom = $1{\text{ }}mole$ atom
gram molecule =$1{\text{ }}mole$ molecule
gram ion =$1{\text{ }}mole$ ion
Avogadro’s number is well-defined as the elementary particles such as molecules, atoms or compounds present in one mole of a substance.
Avogadro's number ${N_A}$ = $6.023 \times {\text{ }}{10^{23}}mo{l^{ - 1}}$
Number of atoms is given as follows
Number of atoms = ${N_A}$ × number of moles or
Number of atoms = $6.023{\text{ }} \times {\text{ }}{10^{23}} \times$ number of moles
sulphur's molar mass is equal to $32{\text{ }}g/mole$
that's $1{\text{ }}mole{\text{ }}of{\text{ }}S \Rightarrow 32g \Rightarrow 6.022 \times {10^{23}}atoms$
so, $2.4{\text{ }}moles{\text{ }}of{\text{ }}S \Rightarrow 6.022 \times {10^{23}} \times 2.4atoms$
$\Rightarrow 14.45\;atoms$

Note:
A mole is a measure of the amount of atoms, molecules, protons electrons and so On.
A mole is well-defined as the amount of substance that holds particles as much as they are present in $12g$ of carbon atoms.
Avogadro’s number is that the one mole of a substance is alike to the molecular weight of the substance. Avogadro's number is a dimensionless extent.
