Question

How many grams of $Al$ are in $4.70{\text{ }}moles$ ?

Answer 1

Mole is a unit measurement. A mole agrees to the mass of a substance that holds $\;6.023{\text{ }} \times {\text{ }}{10^{23}}$ atoms of the substance. Its symbol is mol.
The atomic mass of Aluminium is $26.98{\text{ }}amu$ .

Complete step by step answer:
$1{\text{ }}mole$ of any substance holds $\;6.023{\text{ }} \times {\text{ }}{10^{23}}$ atoms any macroscopic substance can't be existent in this amount thus this number is used to measure microscopic units like atomic or subatomic. Mass of $1{\text{ }}mole$ of a Substance in grams is agreed by its molar mass, also so-called gram molecular mass.
$1{\text{ }}mole$ of atoms exemplifies Avogadro's number, i.e. $\;6.023{\text{ }} \times {\text{ }}{10^{23}}$ . This is basically a number alike $10{\text{ }}or{\text{ }}12,{\text{ }}or{\text{ }}20{\text{ }}or{\text{ }}100$. If there are $\;6.023{\text{ }} \times {\text{ }}{10^{23}}$ aluminum atoms nearby is a mass of $26.98\;g$ . So uncertainty you have $4.70{\text{ }}moles$ , there is a mass of approx. $127\;g\;$ of aluminum.
$1{\text{ }}mole$ of aluminum atoms has a mass of $26.98\;g$ . You have $4.70{\text{ }}moles$ .

Additional information:
Aluminium is a chemical element with the symbol $Al$ and atomic number $13$ . Aluminium is a group $13$ element. aluminium is a weedy metal in the boron group; as it is communal for the group, aluminium forms compounds mostly in the $+ 3\;$ oxidation state. The aluminium cation $A{l^{3 + }}\;$ is small and exceedingly charged; for itself, it is polarizing, and bonds aluminium forms tend headed for covalency.

Note: Generally, aluminum is trivalent. By elevated temperatures, yet, a few gaseous monovalent and bivalent compounds have been organized $(AlCl,{\text{ }}A{l_2}O,{\text{ }}AlO).$ Aluminum is gradually attacked by utmost dilute acids and quickly dissolves in concentrated hydrochloric acid. Aluminum is an exceptional conductor of heat and electricity. Its thermal conductivity is approximately one-half that of copper; this one electrical conductivity, about two-thirds.
